Firefox seems to insist on saving screenshots as .png files, a format
that I loath and detest.

Is there any way I can change some setting so that Firefox will save screenshots as .jpg files?

TIA

PS. I don't want to discuss the particulars of why I hate and detest
.png files either.

Rather than Download, simply Copy the chosen area... open your
favoured image software and create a new (empty) image in the desired
file type. Paste that copied portion into it.
IrfanView is my go-to vehicle.

Windows 7

I use PHOTOED.EXE 3.01. I merely use the Print Scrn button on my
keyboard to get a screen shot, open PHOTOED.EXE, and on its menu bar
select [Edit > Paste as New Image].

While Microsoft no longer distributes PHOTOED.EXE, I archived a copy of
the installer. If you want a copy, reply in this newsgroup thread.

John,

Is there any way I can change some setting so that Firefox will
save screenshots as .jpg files?

Not that I know and/or heard of. Browsers tend to just save the image data exactly as its received, under the name and extension it has been retrieved with (meaning: the contents do not need to be the same as the file extension indicates).

As Nobody said, you could use a image-editing program for it. IrfanView is one of them, but even XP's "paint" program can save an image as several different types - including JPG.

Another possibility is to find yourself a bulk image-conversion program, and use that on the images after you've downloaded them.

Rudy Wieser

There's the standard Windows Snipping Tool since Win7.

Or a very powerful, feature rich capture tool.

I still have Paint with Win 11 25H2... it's handy for changing file

Extensions permit adding, enhancing, or modifying behavior or
functionality with a web browser. There are multiple extensions that
are more robust than the built-in screenshotting function in Firefox.
For example:

https://addons.mozilla.org/en-US/firefox/addon/nimbus-screenshot/
(Not been updated in 6 years)

I remember using that years ago. It was around before Mozilla added screenshotting to Firefox. When Mozilla added screenshotting, it
covered most of the same functions, so I no longer needed the extension.
There are other screenshot extensions available. Just do a search on "screenshot" at addons.mozilla.org.

As for saving in .png versus .jpg, well, you already have media tools
that can do the conversion, like plain old MS Paint on Windows. Firefox
is multi-platform, you didn't mention your OS, but very likely whatever
OS you have also includes some basic image editor. Open the .png file,
and then save as a .jpg file. The above extension lets you choose the
default save format. You don't have to save to a .png file to then open
an image editor to open the .png file to then save as .jpg. Firefox's screenshot tool lets you save to the clipboard, so you save the step of
having to create a .png file, and just load the image editor to paste
from the clipboard.

My guess why Mozilla chose PNG over JPEG is because PNG is a lossless
format (better quality). That is, JPEGs contain less data than PNGs.
In the image editor programs, when you save as JPEG, you choose how much
loss you can tolerate to reduce file size. PNGs are typically larger
than JPGs, because one uses lossless compression (PNG), and the other
uses lossy compression (JPG). You could end up with a JPG that looks
horrible when enlarged, like it gets blurry or distorted. After several
edits, a JPG can look crappy, but quality remains the same with PNG.
You could disable compression when saving a JPG file, but you lose the reduction in size resulting in slower network transfer, and more storage
space needed to save a library of images. However, while a website may
use JPEGs to have smaller image files that transfer faster over a
network, screenshotting is a local-only save, and perhaps why Mozilla
chose PNG for better quality images. JPEGs are limited to a maximum
width and height of 65,535 pixels versus PNGs that are unlimited in
theory (but restrained by memory, storage, and software). PNGs can't
include the EXIF data that can be stored inside JPEGs, but some folks
prefer not having to edit EXIF data to ensure privacy and thwart
tracking. However, since these are images from web pages, they're not
likely to be high resolution, anyway. A guess as to why you prefer JPG
over PNG is due to some handling misbehavior in some program regarding
PNGs, like it won't let you drag a .png file into an e-mail to attach
the image file, but might by using its Insert file menu.

You could go into about:config to search on ".screenshot" to see if
Mozilla afforded any choice regarding save format. There is a browser.screeshots.folderList = 2, and browser.screenshots.dir settings
to where to save them, so there might be other screenshot settings.
However, affording multiple save formats means having to incorporate
multiple rendering engines to generate the different save formats.

I don't see a way to circumvent Mozilla's choice of using PNG to save screenshots. So, if PNGs are so detestable to you, then you're stuck
with having to convert .png to .jpg using some program outside of
Firefox, or adding an extension for screenshotting that gives you more
choices.

https://firefox-source-docs.mozilla.org/devtools-user/taking_screenshots/index.html

From that, looks like Mozilla chose PNG. Up to you to use something
other than Firefox to convert to JPG, like an add-on within Firefox or
an image editor outside of Firefox.

https://bugzilla.mozilla.org/show_bug.cgi?id=1798936

Someone already made your request to save as JPG instead of PNG. Opened
3 years ago. Status is still NEW, so no one has offered code to allow
multiple choices regarding save format.

The nice thing about Firefox's Screenshot feature is that it can
capture the whole page, including what's not visible on-screen.

I prefer PNG format for this kind of thing. It's usually much smaller
than JPG, but I can convert it to JPG if I want (using Irfanview.)

Depends. if you capture a website with photos or only text.

Text only compresses better with png/gif (indexed color).
With photos JPG is much smaller.

ItrCOs a lossless format, unlike JPEG.

JPEG is not only lossy, the DCT compression it uses also develops
interesting blocky artifacts if you push the compression too far.

This is why JPEG2000 uses wavelet compression instead: as that
degrades, the image becomes softer-looking, losing fine detail
gracefully instead of becoming blocky.

I think that you mean "download" rather than paste. Then select the
folder, choose "all files" rather than png, and change the png to jpg or whatever. At least that's the way it works for me in Linux Mint.

You canrCOt rCo at least not natively in Firefox right now.

FirefoxrCOs built-in screenshot tool always saves screenshots as PNG, and thererCOs no setting in Preferences or about:config to change the default format to JPG. ThatrCOs a long-standing limitation.

That said, yourCOve got a few solid workarounds depending on how automatic
you want things to be. Use alternatives or use online convertors.

Ignoring detail would be one.

Extensions permit adding, enhancing, or modifying behavior or
functionality with a web browser. There are multiple extensions that
are more robust than the built-in screenshotting function in Firefox. <Extirpating the rest of Vanguard's usual War and Peace>

I am not aware of FFx being able to save screenshots. I just looked on
all the menus and did not find it.

As Shugo points out, right-click on any displayed page... a dialogue
box appears with "Take Screenshot" as the third option, at least with
Ffox 147.0.2/Win 11 25H2.
Three options result: simples whole page or visible... or drag your

From:

https://support.mozilla.org/en-US/kb/take-screenshots-firefox

I recall that Firefox's screenshot tool uploaded to the Mozilla Sync
service (used to be called Firefox Sync), and why the tool presents a
Download button to get from the sync'ed copy down to your host as a
local copy. The article also discusses Mozilla's privacy policy
regarding the sync'ed screenshots, but no policy would be relevant if
the screenshot were entirely local, and stayed local.

Looks like you can disable any telemety associated with screenshots, but
unless you need to have the screenshots available in other instances of Firefox, like on different computers, seems better to forego Firefox's screenshot tool, and use an extension to do the screenshots.

I forgot Mozilla/Firefox Sync was involved with its screenshot tool.

D.

Remember: Ilias wouldn't let you post anything he didn't approve. Ilias
didn't argue. He blocked or removed your articles without notification
which violated Mozilla's rules regarding admin of their newsgroups (when Mozilla carried them). When I pointed out the rejected articles were
supposed to get modified to denote why the admin, Ilias, didn't like
them, or the rejected articles moved into another newsgroup to hold
them, the Mozilla web page describing the rules on an admin mysteriously disappeared within days after telling Ilias he wasn't following
Mozilla's rules. You were not allowed to explain why a Mozilla product
failed, or why it behaved a certain way, but only describe how to
resolve an issue -- unless you were on Ilias' cronies list. Any
description or analysis was off-topic to the product newsgroup, and was supposed to, according to Ilias, get posted in the general newsgroup to
get buried with posts unrelated to the support newsgroup. You were not
allowed by Ilias to delve into the product, and, of course, never
allowed to berate it.

I gave up on Firefox over a year ago. Scripts at some sites were
exceedingly slow, or would hang, or wouldn't render correctly. All the Chromium variants worked okay. If I were Ilias, I'd have to self-censor
this reply since it berates the product.

As noted by someone else (citing another discussion), Firefox changes
from saving as PNG to saving as JPG. At some threshold, Mozilla decided
JPG should be used to compress (albeit lossy) large images whereas
"smaller" images are saved using PNG. Doesn't look like anyone found a
PNG versus JPG setting in Firefox, so you're out of luck since you don't
want to employ external image editors to convert PNG to JPG, or use an
add-on that gives you a choice on output file format. With limiting
your resolution to only using the built-in screenshot tool in Firefox,
you're limiting your options, too.

I listed a bugzilla ticket where someone requested 3 years to have a
save format option. Still hasn't happened. Has priority P3.

https://wiki.mozilla.org/Bugzilla:Priority_System

You could be waiting 20 years, or more, for the ticket to closed
(usually resoved as "won't fix"), or some code someday gets added to
give you a choice. Don't hold your breath. Probably will show up right
after the second coming of Zarquon (Hitchhiker's Guide to the Galaxy).

With no acceptable resolutions (external image editor, online converter,
or extension), you're stuck with what Mozilla gave you, and that looks
to be PNG for files under some size threshold that only Mozilla knows
about. Instead of clicking Download to save a local copy of the .png
file, why not use Copy? That copies the screenshot into the Windows
clipboard. The format for the pasted version depends on where you
intend to copy the screenshot from the clipboard, but you didn't mention
the destination of the screenshot (beyond mention of the .png file).
You're going to use the screenshot somewhere, so copy-n-paste might give
you what you want without involving any addition software except, of
course, where you intend to deliver the screenshot.

However, albeit another software solution, you could use a different web browser to save screenshots. Edge, a Chromium variant, saves
screenshots as JPG files. I don't have Chrome, but suspect it does the
same. Firefox won't give you what you want. You don't want to employ extensions or external software. The remaining choice is continue using Firefox with its current limitation, or use a different web browser.

As noted by someone else (citing another discussion), Firefox changes
from saving as PNG to saving as JPG. At some threshold, Mozilla decided
JPG should be used to compress (albeit lossy) large images whereas
"smaller" images are saved using PNG. Doesn't look like anyone found a
PNG versus JPG setting in Firefox, so you're out of luck since you don't
want to employ external image editors to convert PNG to JPG, or use an
add-on that gives you a choice on output file format. With limiting
your resolution to only using the built-in screenshot tool in Firefox,
you're limiting your options, too.

Thanks for that information, VanguardLH. But as for using another
program to do screenshots, doing so would require as much effort as
converting the .png images to .jpg using another program. Sure, it's not
that difficult but I'm always on the lookout to find ways to streamline procedures.

I listed a bugzilla ticket where someone requested 3 years to have a
save format option. Still hasn't happened. Has priority P3.

https://wiki.mozilla.org/Bugzilla:Priority_System

You could be waiting 20 years, or more, for the ticket to closed
(usually resoved as "won't fix"), or some code someday gets added to
give you a choice. Don't hold your breath. Probably will show up right after the second coming of Zarquon (Hitchhiker's Guide to the Galaxy).

LOL. You're probably right.

With no acceptable resolutions (external image editor, online converter,
or extension), you're stuck with what Mozilla gave you, and that looks
to be PNG for files under some size threshold that only Mozilla knows
about. Instead of clicking Download to save a local copy of the .png
file, why not use Copy? That copies the screenshot into the Windows clipboard. The format for the pasted version depends on where you
intend to copy the screenshot from the clipboard, but you didn't mention
the destination of the screenshot (beyond mention of the .png file).
You're going to use the screenshot somewhere, so copy-n-paste might give
you what you want without involving any addition software except, of
course, where you intend to deliver the screenshot.

I use Photofiltre and open it with Ctrl-Alt-A.

Don't know why I never noticed that "Copy" button before. That's another
option that will work for me. Thanks!

However, albeit another software solution, you could use a different web browser to save screenshots. Edge, a Chromium variant, saves
screenshots as JPG files. I don't have Chrome, but suspect it does the
same.

Vivaldi does a fantastic job, even opens File Explorer to the location
where it saved the image. However, Firefox is my main browser and when I
need a screenshot, it's usually for a transaction's confirmation window.

Firefox won't give you what you want. You don't want to employ
extensions or external software. The remaining choice is continue using Firefox with its current limitation, or use a different web browser.

Actually, your "Copy" button suggestion will work for me. So thanks again!

But I think I owe you an apology. It looks like the FF people really
thought that users are too dumb to be able to figure out how to use the "startup" folder.

As for the "So, what do you think they ment instead" ? I was thinking of what some MS programs have been doing for ages : pre-load resources
/without/ showing the user-interface.

iow, already having everything in memory/cache, meaning that when the user double-clicks the program everything is already available, shorthening the startup time (pretty-much the same thing you see when having closed a
program and starting it a second time).

Anyway, AFAIK PNG is the better choice over JPG concerning screenshots. (Unless maybe you're taking a screenshot of a video or photo.)

Depends on how the output gets used. I've read (not a problem with me)
where users reported they could not drag .png files into new-email
compose windows in their e-mail software to attach the file; however,
they could use the Insert -> File menu to effect attaching the file.

PNG uses lossless compression versus JPEG which is lossy compression.
Compress too much with JPEG and it starts looking blurry, pixelated, or sheared. Compressing a lot to reduce file size with JPEG often results
in crappy results. Plus, what a recipient sees of your JPEG may not be
what you see. PNG doesn't compress as much as JPEG, so its files are
larger which requires longer transmit times across a network, and have a
larger storage space footprint. However, PNG compression is lossless,
so the recipient gets what you see. Zoom in on a compressed JPEG, and
it gets crappy looking. Because PNG uses lossless compression, you can
zoom in on a PNG or the original a lot more before artifacts appear. In addition, JPEG has a maximum size (width x height) of 65,536 pixels.
PNG has no such limitation. PNG is the better choice unless you need a
much smaller file size after compression, are willing to suffer crappy
quality after compression with JPEG, or incur interference in using PNG
files with some software program. Not all programs support PNG. For
example, when you import or open an image file, .png may not be in the
list of supported file formats, but then you should consider getting a
better substitute for that deficient program.

Mozilla could decide later to save screenshots in WEBP format. That'll
cause friction with many [old] programs that don't yet support WEBP.
WEBP came out 15 years ago, but adoption was not immediate, so figure
WEBP became pervasive for the last decade. WEBP supports both lossy and lossless compression, so you could choose which to use when saving an
image into a file depending on how authentic you want the copy compared
to the original. WEBP produces smaller file sizes than JPEG or PNG.

https://wedevs.com/blog/497396/jpeg-vs-png-vs-webp/

That has a comparison table between JPEG, PNG, and WEBP. The only
deterrence to adoption of WEBP is it requires more processing power to
render the graphic. Nowadays that isn't much of a concern versus the
hardware of clients/workstations some 15 years ago when Google came out
with WEBP.

While some figure adding an output format option when saving a
screenshot is a trivial matter, those users don't understand separate
encoders would be required to support each output format. There are
libraries that could be incorporated into Firefox, but those have code
for multiple formats, and more code than for just one encoder. Well, by extension, and with everyone wanting their own file save format for
their own particular preferences, imagine the amount of code needed to
add all those encoders. Firefox nor any web browser is attempting to
compete against major image editors, like XnView, Irfanview, GIMP,
FastStone, etc. Mozilla added a screenshot option, and elected to
support 1 (or maybe 2) encoders, not every encoder that exists.

use of an app such as "Clipboard to File" (but that only saves as a
*.png)? I doubt that many Linux users have that, but then perhaps
that's why you wrote "Of course real power users use Linux". How do
you save the image as, eg, a jpeg file directly from the clipboard?

So what part of
- Browse to the directory where you want to save it
- Paste clipboard contents as image of your choice
do you not understand?

This is how it works on Dolphin on KDE, no extra apps needed, IIRC XFCE
had something similar.

But your solution is not acceptable to the OP who stated they don't want
to use any extensions inside the web browser, or use external software.
Loading Dolphin to use a built-in regarding saving the current clip into
a file is using external software.

Jeff said to use the clip requires the use of an app. You agreed, but
gave an example of using an particular app (Dolphin). I don't see the
conflict between your two statements. Jeff: use some app. You: use
Dolphin which is an app (file manager). Use an app. You two agree.

Hard to come up with a solution involving solely Firefox and its
screenshot feature when we don't know how or where the OP wants to
deposit or use the screenshot. We weren't told the destination. He may
not even want or need a file, but just insert a clip of the screenshot
in some other program (as hinted by his acceptance of my suggestion of
using the Copy function in Firefox's screenshot which puts the
screenshot into the clipboard).

Absolutely. Before printing, FFx renders the page as the web page
intends it for printing, which can be different than what is on the
screen.

I often find pages that look OK on the screen, but turn into a mess when printed. A couple of common problems are text printed on top of other text and truncated tables (usually if the table is longer than the current window).

Absolutely.

I could make use of a screenshot of the whole page, which is also
different that what I get using the print screen button. I don't see a
FFx screenshot feature. Is it some addon? Or a Windows only feature?

I see "Take Screenshot" on the right-click menu. Selection allows
scrolling. I'm not on Wndows and don't have any extensions for this.

Yes, others have mentioned this and now I do see the thing :-)

There's the standard Windows Snipping Tool since Win7.

Or a very powerful, feature rich capture tool.
https://getsharex.com/

The lastest version hung my system, this works fine:
https://github.com/ShareX/ShareX/releases/tag/v17.0.0

change the output format in Task Settings->Image to .jpg

and in ShareX you can make a "Scrolling Capture", like
FF "Save Full Page" not only the visible window area.

but... of course a power user does this, like in the last 3 decades: >>>>>>

FWIW I installed Thunar and tried that. "Paste into folder" is not
available in that either. Next came Caja, and there's no "Paste into

So without trying other file managers it looks like Dolphin is the odd
one out.

Imagemagick can apparantly convert a clipboard image into a file.

custom action in Thunar.

Extensions permit adding, enhancing, or modifying behavior or
functionality with a web browser. There are multiple extensions that
are more robust than the built-in screenshotting function in Firefox.
For example:

https://addons.mozilla.org/en-US/firefox/addon/nimbus-screenshot/
(Not been updated in 6 years)

I remember using that years ago. It was around before Mozilla added screenshotting to Firefox. When Mozilla added screenshotting, it
covered most of the same functions, so I no longer needed the extension. There are other screenshot extensions available. Just do a search on "screenshot" at addons.mozilla.org.

I am not aware of FFx being able to save screenshots. I just looked on
all the menus and did not find it.

PNG uses lossless compression versus JPEG which is lossy

Actually, JPEG tends to look blocky, because of the DCT compression.
JPEG2000 uses wavelets, which go blurry, which is generally considered

I have even more hatred for Google's .webp format, but then I suspect

like it? (totally ignoring that I clearly said I *don't want to discuss

3. "Use (insert program or file extension name here) to convert the

etc.

Sometimes replies are from people who haven't had their morning coffee
yet (if they drink that marvelous concoction that is) and they neglected reading the entire message I posted. And I can understand that.

Other times, I get trolled. Those people I ignore as best as I can.

Other times people just simply can't understand that anybody would think differently from themselves.

However, sometimes thinking outside the box as VanguardLH did provided
me with an option I hadn't considered -and it will work perfectly for my
needs: instead of downloading the screenshot (and bear in mind that I'm
talking about when I use Firefox's built-in screenshot capability) by
clicking on the "Download" button, I can click on the "Copy" button,
then paste as a new image in my favorite image editing program
(Photofiltre.) Then I can save it as a .jpg file, because that's what
the program defaults to. In fact, before saving the file Photofiltre
opens the compression setting window automatically so that I can set
that level.

VanguardLH understood that I was attempting to reduce the number of
steps needed to save a screenshot in .jpg format and succeeded in
providing a suggestion that actually does that for me.

yet (if they drink that marvelous concoction that is) and they neglected reading the entire message I posted. And I can understand that.

Other times, I get trolled. Those people I ignore as best as I can.

Other times people just simply can't understand that anybody would think differently from themselves.

However, sometimes thinking outside the box as VanguardLH did provided
me with an option I hadn't considered -and it will work perfectly for my needs: instead of downloading the screenshot (and bear in mind that I'm talking about when I use Firefox's built-in screenshot capability) by clicking on the "Download" button, I can click on the "Copy" button,
then paste as a new image in my favorite image editing program
(Photofiltre.) Then I can save it as a .jpg file, because that's what
the program defaults to. In fact, before saving the file Photofiltre
opens the compression setting window automatically so that I can set
that level.

VanguardLH understood that I was attempting to reduce the number of
steps needed to save a screenshot in .jpg format and succeeded in
providing a suggestion that actually does that for me.

Subthreads can and often will diverge into sub-topics. That's how it
works. Just because you asked a question doesn't mean replies must be addressed only to you. We here have fun discussing alternatives. If
you went to a party and asked someone "How are you?", and nothing else
could be discussed thereafter, your discussion would immediately end,
and everyone would be mute for the rest of the time at the party. Not
much of a party without any other discussions.

Actually, that originally was my suggestion/advice... in the very
first response to your initial query.

Actually, you said to copy an area and then paste. That works if the
area to copy is within the current document window in the web browser
without requiring any scrolling. Firefox's snapshot tool does more than
copy an area selected by dragging the mouse cursor. Copy-n-paste works
as you described *if* the web page does not block copying (which is
possibly via Javascript events), and the content resides within the
current view shown in the document window. However, Firefox's
snapshotting tool grants copying more of the document window, and I
believe (this would have to get tested) doesn't care if the web page
attempts to block copying.

Which is exactly why I wrote "the chosen area". There are three
possibilities: full page, visible on screen, or an outlined portion.

It would be interesting to know of any graphics apps that retain any PNG

That's the fault of the software, not of the format.

I haven't tried. When I want exif, the file comes from a camera and will
be jpeg, not png.

Only two of the graphics apps I have installed will preserve Exif data in
a PNG.

GIMP

XNViewMP

Though I can't test this myself, PhotoShop is mentioned as being able to
handle PNG meta data.

There was also a note IIRC, that "Affinity" from what was Serif Software
can handle PNG Exif...

No version of the now abandoned PaintShop Pro can do it.

Apologies... :-/
That's enough off topic side track notes from me.

Schugo,

sorry I thought it was the latest shit.. while doomscrolling
last week.

It's from 2024:

https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

In that year auto-starting of programs on boot also existed over two decades.

Yes, you can put *any* program you like into the "startup" folder,
or put it into the "run" registry key. Thats ancient - as in Win95
old - news.

Assuming that the people at FF also know that, thats likely not what
they ment.

But I think I owe you an apology. It looks like the FF people really thought that users are too dumb to be able to figure out how to use the "startup" folder.

As for the "So, what do you think they ment instead" ? I was thinking of what some MS programs have been doing for ages : pre-load resources /without/ showing the user-interface.

iow, already having everything in memory/cache, meaning that when the user double-clicks the program everything is already available, shorthening the startup time (pretty-much the same thing you see when having closed a program and starting it a second time).

Rudy Wieser

The OS itself is now doing that, for better or worse.

I don't think so.

It would not have a clue to which programs ones you want to have on quick-start, and it definitily will not try to pre-load *every* program it

Yes, it could (the same occured to me), but that won't work well when you
have a multi-purpose machine. Like work and games. It would, on power-up, need to guess what your current intentions are with the machine - or waste time pre-loading stuff that only clogs the available resources.

No, picking out which programs should be ready for extra-fast usage should
be the users, not anyone/thing elses.

In the case where you want to power-down your desktop machine but continue with the current program(s) on next boot there is always the "runonce" registry key. Some programs do that automatically, but, for some reason <cough> very few.

Rudy Wieser

candycanearter07,

File explorer itself is a rather small program, and the decrease in its first-use starting time would be rather unnoticable.

The problem there is that going thru a folder with many files it will cause
a delay (I have a folder which, when first accessed, shows a few seconds of the "I'm looking" flashlight animation).

I'm quite certain you do not want file-explorer to go thru all drives and folders and pre-load all the files meta-data. It would cause a *lot* of delay on boot and waste *lots* of memory/chache space.

And that besides the delays / problems remote disks could/will cause.

and it i think was causing issues

:-) I can imagine.

Rudy Wieser

Then the work and games apps would show as having half the expected

That's another strategy. The preload admin could be configured to auto
or manual. And auto would have thresholds.

I would at least default to a lossless format, if not use it
exclusively. ItrCOs easy enough for the user to convert to something
else; if they can enter a command template in place of an output
filename template, even better, e.g. for a simple output filename:

-2screenshot-name-+.png

whereas, to save as JPEG, you could use:

| magick convert - -2screenshot-name-+.jpg

Note the rCL|rCY at the beginning to indicate the output file is to be
piped to the given command.

Is there any way I can change some setting so that Firefox will save screenshots as .jpg files?

That would be one way to keep you happy without limiting the
possibilities for those with more imagination.
