After a Windows 11 update, Firefox does not automatically start although set to do it and when I start it, a small rectangular box appears in the upper left corner of the screen.

Please resolve.

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I am trying to organise my Firefox bookmarks into folders on my Mac Studio. However, when I try to use the highly-touted "just drag and drop advice" it does not work. It doesn't work in the drop down and it doesn't work in the bookmarks manager. Drag and drop functionality works elsewhere on my Mac just fine.

Note, if I open every single bookmark, click on the blue star, then re-assign the folder it does work. However, that it a mighty pain in the arse.

Since I know it will be asked...'yes' both Firefox and my MacOS are up-to-date. And 'no' I haven't upgraded to Tahoe.

I would appreciate any help that anyone can offer. Thanks!

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

I just bought an HP Omnidesk M02-0085m PC running Windows 11 Home edition. For some reason Prime video works in other browsers, but in Firefox I get audio and a black screen. I am not using any ad blockers and I have tried toggling performance settings on/off. Any suggestions?

I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

I just bought new PC and switched to win11(never happened on win10). Videos stutter when on 2nd monitor and game is open on first, but audio doesn't. Problem goes away immediately when clicking to the firefox window. Happens on both youtube and twitch, but not on Nebula.tv and not on chrome. Doesn't happen if the video is 480p, but does on 720 and 1080 and both of them are 60fps which might be something. Also doesn't happen if the game is windowed, but does on fullscreen and borderless.

I've disabled hardware acceleration (in windows and browser). I've tried setting both monitors to 60hz, setting firefox priority to high (and game to low), disabling effiency mode, setting power mode to performance and tried a lot of other things including about:config settings. Also ruled out extensions.

How can I get all Firefox settings as a simple table? I am sure that is how they are kept by the program, somewhere outside the Firefox UI. Are they kept in the System Registry? It would sure make troubleshooting & continuity easier when moving to new devices/CPUs.

Hi,

I told my banking site to trust my computer but I changed my mind and want 2fa back. When I go to my banking site using chrome, it uses 2fa so I know it is not on the banking site.

What do I need to do for firefox to start using 2fa for this site again? It says firefox browser is up to date and I'm using Windows 11. Thanks, Steve

Meine Firefox-Rahmen (Menü oben und unten) sind rosa eingefärbt und im Text auch unterlegt. Ixh möchte wieder das gewohnte Hellgrau. Das funktioniert aber leider nicht über Einstellungen und add Ons. was ist zu tun? Ansonsten wechsele ich auf MSN

Recently google's advanced search page changed from how it's been displayed for years -- seemingly only on firefox. And I hate the change. It still displays as always on DuckDuckGo and Safari. Firefox is my preferred browser, but I use goodle advanced search myriad times every day and this is changed version is such a PITA that it's approaching being a dealbreaker for me. Sure, I'd like to know wth happened and why, but really I just want google advanced search to return to my preferred display. (It does not just look different, it performs differently, in little ways that matter a lot to me over the multiple times I use it. Be glad to elucidate if it matters.) First attached image is what I'm now getting on ff. Second attached image is what I used to get on ff, and still get on DDG and Safari, and would like back on ff. Please help.

In Settings>General>Language, why is there an option to "Use your operating system settings for “English (Zimbabwe)” to format dates, times, numbers, and measurements." . I can't find any documentation for this. Is there an interesting 'Zimbabwe' format or feature? If so, what is it?

Do I need to add an email filter?

I have firefox as my default browser with Bitwarden extension. I use yahoo and sign in for browser. I also have outlook for email. Maybe a month back, when signing into yahoo, I would type in the first few letters and bitwarden login options would appear. They still do but selecting one seems to do nothing now. If I open bitwarden and try autofill from the login file, it says it cannot autofill, items must be copied and pasted. Its odd that in yahoo home page login the options appear but do not autofill as they used to maybe a month ago.
