Firefox Community Forum

Firefox on Windows 11. When I try to open Firefox I get a message that Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. Close does nothing, Task manager - end process does not close. Stuck in a permanent loop here. Rhonda

Beginning with September 2026, Mozilla Firefox browser - version 115 - does not work on Win7 anymore, although mozilla.org says that it should work until March 2027. Any explanation or solution? (I won't use Win10 or later versions ever.)

The problem: Version 115 can be installed, but after that Firefox browser does not work at all. Not only as internet browser, but even "settings" cannot be open. It's a dead program.

I installed Maxthon instead of Mozilla, because the Chinese browser supports Win7. This older version of the Windows is still perfect (!) for everything I use: internet, videos, Open Office, etc. However I have to select between ad blockers and browsers. My printers also works on this version of Windows.

When I cannot use Win7 anymore on the internet I will choose Linux instead of Win10 or later versions.

I've rebooted, even did a hard reboot, total 3 times, tried system restore, 1 hour past update, deleted Firefox, reinstalled, still "in use", deleted Norton, still same. Reinstalled norton. There NO BUTTON, SWITCH, there! I can File, new blank page, still nothing. Sort of reminds me of automakers, all look alike! Left side, simple, turn on sc or import, at the opening first time, import short cuts and bookmarks from previous page, turn off Newsweek. Simple, without the hassle of now, those that have cleared, happy for you! For me same thing at the top, yellow bar, "in use!"

I've installed Firefox on my Ubuntu installation (on USB) but for some reason, it doesn't work. First time i tried opening it, just said it crashed/closed unexpectedly, and all of the other tries i've now attempted, still don't work. Maybe it's because i'm running my Ubuntu on a USB? (sob) I don't really know, can someone help?
