At least once a day since Version 145 dropped Firefox has told me I need to restart to update. When I do, it shows a pop up telling my I am opening an older version of Firefox and need to create a new profile to avoid corrupting my data. Daily, sometimes twice a day I have to go in and switch profiles back to the profile that has all of my book marks. Every computer in our office has this issue now. One of them deleted a profile without prompting, and it is not even in the appdata folder with "deleteme" in front of it. It is just gone. The last update had tabs crash daily. Is there any hope of stopping the second broken update in a row from wasting my time fixing it every day?

After the 8/5/25 Firefox update the internet is inaccessible on my laptop through the standard Firefox browser. The internet is accessible with MS Edge. Toolbar is set to always show bookmarks but none appear. Also, the browser's application's menu does not open to access options such as restore previous session, recently closed tabs, etc. I've restarted my device several times without it resolving the issues with the standard browser.

The Firefox developer version opened in command prompt safe mode (firefox -safe-mode), which is how this inquiry is being sent, but no bookmarks on tool bar or current page history from the standard (non-developer) Firefox.

I'd like to return to accessing the internet using the standard Firefox version with its bookmarks, history, etc. I am using Windows 10. Thank you.

I have taken the position of never installing updates of firefox in windows 10 because of the following: after EVERY update, within 20 minutes of activity my mouse freezes. Keyboard is inactive. I have no option but to reboot. Windows displays "repair mode" 2 HOURS LATER ! the pc finally boots. This happens after EVERY upgrade. Since I have stopped upgrading, the pc behaves.

Never seen this before. I installed v143.0.4 on 10/3. Since it was an extended length of time up to now, I went to check (Image 1 & 2)

I still wasn't convinced (Image 3)

Also, I never opt to "Automatically Install Updates". I don't know how that got selected, but even so, it did not work.

Explanation please?
