Firefox Community Forum

whenever i stop, backtrack or advance a video as in youtube i can expect it to crash. the same with pages containing videos. also playing music sound clips i can guarantee a crash. this has been a problem for years.

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

Firefox comes up in a large window, covering most of my screen. I can resize the browser window just fine, as expected. However when I close the program, then open it later, the browser window is not the size and position it was in when I stopped the program last, it comes up with a large window again.

Tonight I received a notice that a new version of Firefox was available and asking if I wanted to download it. It showed me the new Kit mascot so I decided to let it install. It seemed to install normally but when it tried to open what I guess is a welcome/new features page, it crashes, and just showed a prompt to try again. This continued in an endless loop and I had to shut it down. Unfortunately I no longer had a functioning version available that I could find so I downoaded the ESR version to be safe (ver 140.5.0esr) which I am now using. Somehow I was able to recover bookmarks and hopefully other saved info. Can anyone advise what has happened? I have used Firefox for many years and never had this sort of problem before. Running Windows 11 on a new Dell i7 PC.

With the latest update when I open a FF browser window the title bar does not have the 3 icon for Shrink. Resize of Close. To get these to appear I much click on the tab for the window on my Taskbar to make the browser window close and then click again to reopen it at which time those 3 control are back where they should be.

Why is this happening after using the browser for many many years? This is really annoying and I do not understand what you all did to mess things up or if i can fix in on my end.

Is there a button I push or a feature I enable to make sure that I'm opted-out of any future updates that include AI 'features'? Or should I switch to Vivaldi now and save time?
