Since about a month (after I updated Firefox),
I have problems with closing Windows 7 when I used Firefox
(now Firefox 115.31.0esr 64bits).
I see a BSOD with a lot of text, mentioning "Bad_Pool_Header", "Page_Fault_in_nonpage_area", or "System_Service_Exception".

I have no idea what that is and I do not understand what to do.

Workaround is let the PC start again in "Veilige Modus" (Safe Mode)
and as that is finished, just close it down.

Sometimes I get the BSOD when I'm just doing something.
In that case always Firefox is active.

What can I do to repair this?

Could be faulty RAM, leave memcheck running overnight, if that doesn't
find any errors, look for updated GPU drivers ...

I do not know about memcheck or GPU drivers.

Is it this?

Or is memcheck somewhere in Windows 7?

yes, it has to reboot to shutdown win7 and get into memcheck itself, let
it run overnight

Or is memcheck somewhere in Windows 7?

Or you can run memtest86 from a USB stick

Not an answer to your question, but you are aware that 115.x is the last version of Firefox which will run on Windows 7? https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

For Windows 7, apparently there is an "mdsched.exe" as the entry point.

An alternative, is to add a boot menu, then in the boot menu, tab
to the bottom to select it. Takes maybe 5-10 minutes.

For the boot menu:

1) type "cmd" into the run box, the search finds it, then right click and "Run as Administrator"

2) bcdedit /set {bootmgr} displaybootmenu True # It should say operation completed, after you hit return.

3) On the next boot, the old fashioned boot menu appears.
The timer is usually set to 30 seconds by default.
Use the <tab> key to advance to the bottom menu item.
The same memory test as mdsched.exe should run.

Or is memcheck somewhere in Windows 7?

When The BSOD appears, does it have a driver name ?

The driver name might begin with "nv" and it is
an NVidia driver problem.

Your problem description suggests:

"disable hardware acceleration setting in Firefox"

Some hardware/driver combinations, may not be the best
for working with Firefox. In such cases when instability
is a side effect, you can try turning acceleration off.
In this example, I have unticked both boxes (unticked top
one first, then second one appears).

Settings : General : Performance
__
| | Use recommended performance settings
--
--
| | Use hardware acceleration when available
--

See if the box stays up a bit more, when FFx is set that way.

We've had some fun with this in the past, when Firefox would
not stay running long enough to use that interface...

That's why he uses it and looks for alternative Browsers.

Thanks Paul,

I unticked both boxes and will see if the BSOD is gone.

Possibly you got an update to your video drivers. Did you leave Windows
to automatically update drivers? Don't do that. To update drivers, get
them from the hardware manufacturer, not from Microsoft. Disable
automated hardware/driver updates in Windows.

Disable hardware acceleration in Firefox. That uses the GPU which means Firefox is using the driver to access the video card, and sometimes how
Firefox thinks it can do accelerated computation is not what the video
card maker implemented. Hardware/GPU acceleration only some slight
effect then playing online video games inside of Firefox.

If you have a Samsung m.2 NVMe SSD, you might also have installed their Magician program. A feature it present is RAPID mode: a driver they
install that will accelerate the SSD under very rare scenarios, like for benchmarking. Do not use Magician's RAPID driver.

What's "stupid" about R Daneel's reply mentioning that FF 115 is,
effectively EOL for Win 7??

If nothing else, it makes Rink aware that there could be bigger and
better problems around the corner.

It looks like this is the solution for me.
After unticking these two boxes, I haven't seen a BSOD.
Even not while switching off the computer two times.

I do not automatically update drivers.
I even did not update Windows7 for about 5 years.
I do not want W10 and certainly not W11.
Thinking about Linux (Mint?) but I have no experience with other OS's.

Paul gave this advise too on Jan 6th.
It looks like this is the solution. I haven't seen BSOD's after I
unticked those two hardware acceleration boxes.
