Apparently Windows 11 won't upgrade from v23H2 to 24H2 because the very nice cpu (and system) don't support SSE4.2 or PopCnt instructions. While v23H2 won't get updates after November of 2025, I tend to use operating systems WAY beyond no more updates without problems, and only upgrade when browsers no longer update and support some websites, notably banking and credit card sites, for example.

Any way to get at least a rough idea of when/how long Firefox will continue to update on Windows 11 23H2 so I can plan ahead? Usually it's a year or 2 or more after Microsoft stops updating the OS.

Thanks.

Good day! Initially, I installed Firefox version (x64 ru) 147.0.3. After updating via the "Help - About Firefox - Update" menu, I received version 147.0.4. However, there are two entries about installed Firefox in the Windows section "Installed applications": 1. Mozilla Firefox (x64 ru) 147.0.3 and 2. Mozilla Firefox (x64 ru) 147.0.4. Although one instance of the program is installed. How do I remove an extra entry? Thank you.

PS: I have Windows 11 Pro 25H2 (26200.7840, 1000.26100.291.0) Russian CPU AMD Ryzen 5 5600X 6-Core Processor RAM 32,0 ГБ System x64 Video NVidia GeForce 1650

I just received an update to FF 137 and my userchrome.css which is set to show tabs BELOW the toolbars (i.e. a logical place above the relevant pages and not halfway up the toolbars etc.) has stopped working. Checked the toolkit.legacy etc and it's still enabled.

Any ideas to fix this are welcome.

I try to update Firefox once a month, but every 6 hours I am notified about the release of a new version, so I have to click Cancel. Is it possible to increase this interval (at least to 24 hours) or disable it altogether?

I tried changing settings "app.update.interval" and "app.update.background.interval" but it didn't help.

I've been using Firefox for a while now, and I heard there's a new update available. I'm curious about what new features or improvements have been added in this latest version. Is there a summary of the key changes? Also, are there any significant performance enhancements or security updates that I should be aware of? I want to make sure I'm taking full advantage of the latest capabilities. Any insights would be appreciated! Let's discuss more about this!

What does this mean? being updated by another instance

Is this why my FF is running godawful slow today?
