Diễn đàn hỗ trợ Firefox

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

A while back the behavior of the ctrl+shift+t shortcut changed from reopening tab in the current window to reopening tab in the current window or reopening last closed window which for me and a lot of other people too made it worse. There's been a thread https://support.mozilla.org/en-US/questions/1421356 but it's been archived without a real solution. Is there now a way like a about:config toggle to bring back the old functionality? I really miss the old behavior.

Hello,

My password saved are deleted every time I close FF. It used to be manageable because Google and other sites didn't require me to fill my passwords (cookies did the trick I suppose) but now I also loose access to gmail and Youtube every time I close FF. It's annoying to have to use 2FA every damn time. And keeping the passwords available.

I've tried every answer I found by looking around :

- tried to start in safe mode - disable hardware acceleration - I have no extensions

FF saves the passwords correctly (at least they appear in the saved password tab) but they are erased every time I restart FF. The cookies aren't automatically deleted (FF remembers my browsing history) but I need to relog into Google.

I getting frustrated.

Ever since I switched to Firefox a few months ago, i've noticed that the audio on youtube music vids cuts out when I put the video on a loop sometimes. Moving the play bar to a different point/time on the video fixes it but it is extremely annoying. Can anyone help with fixes? Thanks

Firefox 126.0.1 displays a very long name of a container completely in the URL bar.

Firefox 127.0 truncates container names

AWS long account and role names make keeping the long name very convenient (works with the 'AWS SSO Containers' Add-On

Hello! Google won't keep me logged in onto their services on Firefox, so that means for every time i open up Firefox I have to re-log in. I don't know why this happens, and I want to keep myself logged in onto google services but I don't know how to toggle it. Please help thank u!

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks
