Although Firefox will no longer run a JRE as a plugin for web content, Firefox should be able to download a JRE installer for other programs that need it. You just would not notice any change in Firefox itself after installing Java. And I think that's fine because your office suite isn't dependent on any specific browser.

Thanks so much for your reply Jsher. I didn't see it b4 today - I was looking in my Inbox. :) Before you read this I must apologize. Sorry I'm so inexperienced - embarrassing - but I've been ill over 22yrs now. I'm not being obtuse I just have cognition issues with pain signals interrupting my thoughts. I get it I just can't remember/repeat so well. Please be patient with my questions.

I did go to the JAVA home page b4 - but I got an error just navigating there: as follows:

We have detected you are using the 64-bit version of Firefox which will not run the Java plugin from this browser. More info. =>

Firefox no longer provides NPAPI support (technology required for Java applets)

As of September, 2018, Firefox no longer offers a version which supports NPAPI, the technology required to run Java applets. The Java Plugin for web browsers relies on the cross-platform plugin architecture NPAPI, which had been supported by all major web browsers for over a decade. The 64 bit version of Firefox has never supported NPAPI, and Firefox version 52ESR is the last release to support the technology. It is below the security baseline, and no longer supported.

Java applications are offered through web browsers as either a Java Webstart application (which do not interact with the browser once they are launched) or as a Java Applet (which might interact with the browser). This change does not affect Web Start applications, it only impacts Java Applets.

Developers and System administrators looking for alternative ways to support Firefox users should see this blog regarding Launching Web Start applications. RELATED INFORMATION

That's gibberish to me now after working a long time on my PC...

Are you saying I SHOULD just download the "download" icon on the home page they gave me referencing only FF? Will that do it? It doesn't mention the download is for the JRE File. JAVA only auto detected FF. ...lets see what JAVA said in reference to FF:

64-bit Java for Windows Recommended Version 8 Update 321 (filesize: 81.99 MB) Release date: January 18, 2022 below it says:

Agree and Start Free Download [ not sure what it is but okay...]

By downloading Java you acknowledge that you have read and accepted the terms of the Oracle Technology Network License Agreement for Oracle Java SE... [too hard]

So it's Oracle Java SE...but it also needs to be...64-bit Java for Windows Version 8 Update 321 (filesize: 81.99 MB) Release date: January 18, 2022. I don't know what that is for since it only referenced autodetecting FF and nothing about OfficeLibre. So I'm just not getting it.

I guess I'm confused because the java download doesn't say it has the JRE file. Is JRE included in JAVA SE 64X Win ver8 321?

Will JAVA SE 64-bit Java for Windows Version 8 Update 321 make OfficeLibra work only by itself? Or is there another JAVA file I need to download that I can't find to transfer files from FF/web?

Will transfers btwn FF & OfficeLibra work with the same Java d/l they reccomended detecting only FF or not? Or is there another download I need for that and from where?

Specifically, will JAVA download ...whichever one you or they tell me to ...work to transfer data either; manually (copy/paste), or automatically transfer data between a FF operation/page like documents or FF Help pages or an internet webpage or an email transfer?

Much obliged to your advise - thank you much.

Copy and paste is a function that uses the Windows clipboard, so I don't think Java is needed for that at all. For transferring data, it depends on how LibreOffice works. It might use Windows functions rather than using a browser. I guess if you run into a problem, let us know.

Regarding whether the Java package will make LibreOffice databases work, that question probably would be better directed to LibreOffice support. Either way, Firefox will not be involved except as one method of downloading Java for other software to use.

The Firefox web browser has never need a Java Plugin from Oracle to work as a web browser. It also has not allowed the Java Plugin (NPAPI) to run since Fx 52.0 Release.

Why do Java, Silverlight, Adobe Acrobat and other plugins no longer work? https://support.mozilla.org/en-US/kb/npapi-plugins
