Been using on my computer but will not work on a new computer.
Appears to be a JAVA problem with FireFox dumping it. Any
suggestions for a replacement?

From https://www.rssowl.org/, it notes the JRE (Java Runtime
Environment, basically the runtime library for Java) must be present, so
you may have to install it separately. "Computer" doesn't identify the
OS. Java hasn't been bundled on Windows for a long time. You would
have to visit Oracle to get the latest JRE. The RSSowl site points to https://www.java.com/en/download/manual.jsp. You don't need the much
larger JDK (Java Development Kit), just the JRE.
Don't know what Firefox has to do with RSSOwl which looks to be a Java application, not a Java-based web app. While Firefox, as with almost
all other web browsers, support Javascript, they stopped supporting Java
a long time ago. Javascript is not Java. Installing JRE in the OS
won't make the web browsers support Java, by default. You have to
enable Java in the web browser. Oracle has an article on enabling Java (again, not Javascript) in various web browsers, which is at:
https://www.java.com/en/download/help/enable_browser.html
Do you really have to load a web browser to then run RSSowl as a Java
applet inside the web browser (after enabling Java in the web browser)?
Maybe there is another reason RSSowl stopped working for you. See:
https://github.com/rssowl/RSSOwl "RSSOwl is unmaintained and has several known vulnerabilities. Please do not use it any more."
"Furthermore, RSSOwl does not work with Java 9, but it may still work
with Java 8."
The Java download page has only 8 as the latest released version.
https://en.wikipedia.org/wiki/Java_(programming_language)
"Java 25 is the version current as of September 2025. Java 8, 11, 17,
21, and 25 are long-term support versions still under maintenance."
If you have other Java apps needing later versions of Java, there are
tricks to having multiple JDKs installed (do a web search), but I don't
know about having multiple JREs installed. Haven't used Java, or
anything needing it, for about 2 decades. I forget when MS decided to
stop bundling their Java in Windows, so Java applets either made their
users separately download and install Java, or bundling Java with their installer.

I've recommended RSSOwl in the past to Windows users (I don't know if
the OP has Windows) and I wondered if it still worked in Win 11. So I installed it to see:
<https://www.rssowl.org/>
It reported no JRE so installed v8 from here: <https://github.com/rssowl/RSSOwl/issues/17>
And it works fine. As VanguardLH wrote, multiple JREs can be a
problem but not on this box.
FWIW I normally use Sparse RSS Mod on Android or liferea on Linux.
And occasionally NewsNetWire on iPhone and MacOS.
