Firefox Community Forum

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?

It is with deep regret to inform you of my discontinuation of the use of Firefox.

My issues began at the beginning of February this year and have continued and compounded to the point that I cannot continue its use. The issues are constantly logging me out of my account, disabling ALL my bookmarks and the loss of well over a hundred passwords. I have followed every help article and community forums help links and to no avail I'm still dealing with all the same issues. I've have to restore my links every time I'm logged out of Mozilla. Their are no passwords to restore except for the Mozilla account I just had to log back into.

Again, I do regret discontinuing its use. I have used this browser for well over a decade and I am not one for changing anything at this point in my life. I'm 67 and having to switch is indescribably painful. I actually think your integration of AI functions are the problem. Everything was just fine before that was introduced.

If you have any comments, please feel free to email me at my former account email address.

Farewell old friend.....

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Popup GUI elements if pulled up twice in quick succession spike my CPU usage and crash the program

some examples: -menu bar menus -the menu button -context menus (websites with their own context menus do not do this) -preview tooltips

I've tried disabling extensions, turning hardware acceleration off and on and disabling AI to no avail. Disabling the preview tooltips 'worked' but I'd prefer not to disable everything here. Are there any other settings that might help?

I still have windows 7 pro on my computer and now I keep getting "Access Denied" from some websites Can your ESL be used on my computer so that I can access my bank; stores, etc.?

Since last two updates, I noted I can't click on the URL field or any icons next to each other two versions ago. I changed the Bluetooth mouse to a lined mouse, then it went OK. But with the latest update, again, the same symptom occured and persists: I am on MacBookPro, so I manage to Command+any command key.

How can I restore and click on URL field, copy URL, or reload the URL address again? OF course, I need to use other icons for each function.

Hello, I'm using Firefox 147.0.4 on Windows 11. When I open the Adobe Firefly website and I try to upload a file to the Adobe server using drag and drop or by browsing the Windows file system, nothing happens ... There's no error message, but the file isn't uploaded. Of course, this site works perfectly with Opera or Edge... On the Adobe forums, many users have the same problem with Firefox, and Adobe's response is always the same: change browsers ! Thank you for keeping me informed about the resolution of this problem, as I don't want to change browsers ! My email address is [edited email from community support forum]

Have a great day, Sincerely,

Mr. Fernandez

Today, "prioritized email" notifications started to show up in the lower right hand corner of the monitor. They are very annoying! How do I prevent from appearing on the screen?

I tired to log into my FIREFOX account by my usual way which is tapping the logo. A new screen ask for permission to make changes to my FIREFOX website. although I said NO , it continued to install UPDATES and UPGRADES that I do not and that I am unable to undo.

I have tried to restore or or recover my former FIREFOX WEBSITE , BUT NOTHING SEEMS TO WORK. I think the changes are the the results of an AI takeover.

i switched from MICROSOFT EDGE to FIREFOX when things like this began to happen.

Please , help me retrieve my former FIREFOX website. I spend a lot of time on it, and I HATE the "UPGRADES?"!

I am experiencing significant performance problems in Mozilla Firefox when using certain AI-powered tools. Below are the specific issues:

   Flux AI & Diagramming AI Performance Warnings

       Issue: When accessing Flux AI or Diagramming AI tools, Firefox displays a warning message stating, "This site is slowing down Firefox."

       Observed Behavior:

           Delayed response times or freezing when interacting with these tools.

           High CPU usage (observed via Task Manager) when the tools are active.

       Expected Behavior: Smooth operation without performance degradation, as seen in other browsers (e.g., Chrome or Edge).

   CMS Sign-Out Failure

       Issue: Unable to sign out of my Content Management System (CMS). The action either freezes or refreshes without logging me out.

       Troubleshooting Attempted: Cleared cache/cookies, disabled extensions, tested in Safe Mode—issue persists.

   ChatGPT Menu Error

       Issue: Clicking the three-dots (⋮) menu in ChatGPT triggers an error instead of displaying options.

       Error Context: Mentions "Flux AI," suggesting a possible conflict or integration failure.

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"

So, after using firefox in the background to browse websites or watch videos I checked my memory usage in firefox with about:memory -> Measure and saw that youtube was consuming a decent amount >2GB (checked the main url when clicking the youtube src, it was the video on that sole tab i was watching and nothing else playing youtube in the bg) so i closed that tab, waited a bit and re-measured but then see that the memory usage for youtube rose about 200MB... and the website for youtube is that same url for the tab that i just closed (when checking the src in the results for Measure). I've been revisiting the about:memory page, reloaded it and re-Measured and youtube is STILL THERE. Even now, 10 minutes later i still see youtube there, with none of my tabs running youtube.

If i close firefox entirely and re-open my tabs then it'll very likely fix it but this has to be a major issue no? I shouldn't have to close the entire browser program just to fix a website visit, which is youtube of all websites.

As of this moment, firefox, with 8 tabs open, is consuming 4,452.99MB (~4.5GB) where 2.5GB is youtube for that page i closed.

I don't know if sharing memory reports from the about:memory page give my cookies away or leave me open to a similar vulnerability so I won't share it unless a dev or similar asks for it but for now, I've included an image showing all the tabs i have open on firefox, 2 windows.

Hello there

I'm running version 146.0.1 (64 bit) on a Windows 10 machine, and I've found that trying to use printscreen now opens Firefox. I cannot discern why, if it's a Windows setting or a keyboard issue or anything else

things I've tried:

- Disabling every extension - Disabling AMD Radeon - Disabling ShareX (My normal screenshot program) - Factory resetting my Keychron Q6 Max (in case there's some weird macro that got set up)

Any ideas? This might not be a firefox issue, but I figured I'd ask here. Thank you
