No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Hi,

My Firefox had auto updated to the newer version with AI built-in and auto-enabled, which meant the browser would crash EVERY. SINGLE. TIME. I would launch it.

For perspective, I am running an old Lenovo Thinkcentre mini PC with an Intel i5 6th gen and 16gb of ram; its got Windows 11 installed, and always running out of memory with the simple things like browsing and word processing. This is NOT a PC or use-case that needs or warrants AI.

So, I uninstalled Firefox (149) and installed the latest version WITHOUT AI built-in (147).

I then synced my profile, and things ran fine. An hour passed, and then i kept getting an error, saying my profile was created with whatever and I need to create a new profile.

So, I created a new profile and synced, again, and I got the error, AGAIN...

I'm about to boycott Firefox on all the devices I control, and opt for an older version of Opera or something more obscure, so that I don't have to deal with this nonsense.

I am making another plea: how do I change the font size of the working bars in firefox? The Title BAR, the Menu BAR, the Tab BAR, etc. On my computer, they're minuscule, and I can't see them. I'm not a programmer, I don't know anything about code, so that limits the way things can be explained to me, or that I can understand. Several of you have been kind enough to suggest different solutions, but they all make things worse. I think I've screwed things up almost irreparably. I can barely recognize my browser any more. I've even tried to refresh Firefox, and that also made the situation worse. And now, every tab crashes constantly. Thanks to anyone who can help me solve this problem.

After clicking the "Set up free VPN now" button, the explanation page with the individual steps appeared, but I couldn't complete the process because the setup prompt was not visible in the browser.

Hello! I've always used Firefox as my default browser. Now, with Windows 11 Pro, I can't get it to stay as the default. I restart my computer, and Edge reappears. I've tried adjusting registry, gpedit, Taskschd, etc., and Edge remains the default, even for PDFs! Is there any way to change Edge?.. I don't know what else to do to set Firefox and Acrobat PDF as the default. Microsoft is forcing Edge as the default. Thank you!

Every time go to Firefox home page (clear browser settings), I get "Account Disconnected" message.

I have another PC with the same Firefox browser homepage and do not have the problem.

Help or suggestions appreciated. TU for reading.

When using Firefox and clicking on a link oftentimes instead of the link opening in Firefox it opens Microsoft Edge. I have Firefox set as my default browser. Other than uninstalling Microsoft Edge is there any other solution to this problem? My OS is Windows 11 Pro.

how can i force the active tab to show? i am fairly sure this feature was in a previous edition. I have a large number of tabs and sometimes an app or video will start and i am forced to go back and forth thru all the tabs just so i can stop them.
