I-Firefox Community Forum

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?

Hi, I have a disaster situation. I backed up my profile and then I wiped my computer running Ubuntu 20.04. I replaced it with Ubuntu 24.04. Now my profile seems to not be compatible with the Firefox installation on Ubuntu 24.04.

I followed this official instructions: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I put my old profile in the ~/snap/firefox/common/.mozilla/firefox/ folder and I set the correct values in profiles.ini. But sadly when I start Firefox all my passwords, extensions and history are not there. I lost everything.

I'm super desperate. Please tell me I can fix this somehow. Why is the official documentation lying?

Fx 124.0

Why am I getting these notifications? I have the latest version, but this prompt not only asks me to update, but there's no mention that it will install the beta 125.0 beta 1

I first mentioned this in r/Firefox, and was asked to re-post here.

My FF just updated to 127.0.1 even though I have "Check for updates but let you choose to install them" and told it to wait. This was on a Windows 11 box. Everything seemed fine, but then one of my tabs crashed. I selected the reload tab option, at which point it informed me it could not load the tab because a background update had happened and I was now required to restart Firefox.

I'm not certain what version of FF I was on, I believe it was either 126 or 126.0.1.

Now, to be completely fair, I cannot with 100% certainty say that I clicked on the update later option. That said, as I _did not want to update then_, and I have put off the update before, it seems unlikely I would have made the mistake, but I wasn't recording everything I did so I can't play it back and prove it. My initial reaction was to associate it with the tab crashing somehow, as everything was working as expected right up until that moment.

Thanks

i have for over 7 months that i have multible firefox crashes during the day, i only uses the pc for gaming, but now also for other stuff and use firefox for it.

Can anyone help me out ? and if more info is needed i would be happy to share, as long as this problem can be solved

Outlook.office.com not refreshing automatically anymore and requires browser refresh to show new e-mails, etc... Works in Edge and Chrome just fine. Had this issue years ago and issue self-resolved, so unsure what resolution was then.

This problem is NEW ... I've been using Firefox with Bible Gateway for literally YEARS, and this problem has begun in the last two days. I tried to follow the advice under other occurrences of this problem to others, and couldn't ... I don't get into code that way!

All I know is that I can no longer simply open a tab, go to that site, and use it; once that error shows up, no navigation on the page is possible.

Idk whether this is a problem for Firefox, or for Bible Gateway. I've contacted them, too.

But ... what can I do?

I have had Firefox installed as a backup browser on Windows 10 Home Edition. Due to some strange and possibly non-resolvable issue, I keep having a problem with the Crash Reporter popping up stating that Firefox has crashed, even when Firefox has not been running *at all*. I updated to the latest version of Firefox; this resolved the problem for a few weeks but then Crash Reporter started popping up again. I might mention that when I do actually run Firefox, it comes up and runs fine, with no problem or crashing. I would like to know if there is some relatively simple way to disable the Crash Reporter itself from coming up.

I keep getting the error in the image and can't use my tabs at all . The search loads for 10-15 seconds and then I get the error. I have tried troubleshoot mode too !

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

Hi,

I have used Firefox for a long time. I have many bookmarks, passwords etc on Firefox on my original PC.

Sadly the hard drive on my original PC has failed. I borrowed a laptop temporarily and signed into Firefox on that. My bookmarks did not transfer across and instead I had someone elses bookmarks but I wasn't too concerned as I was only borrowing the laptop.

I now have a new PC. I have restored my files from a backup external drive and I have signed into Firefox on this PC. However, all of my tabs and bookmarks have not come across. I have pressed sync but it has brought the bookmarks over from the laptop and not the bookmarks from my original PC.

How can I sync to the original PC that has all my bookmarks etc please? Or have I lost it all forever?

Thank you.

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.

I am running Mac Big Sur, 11.7.10. When I am in Firefox version 127.0.2 and I go into any Google search, the tab crashes. It works in private browsing mode and also in other browsers but not in non-private browsing in Firefox. I have tried disabling extensions, add ons, etc. Nothing seems to help. This started happening a few weeks ago with any YouTube page also. How can I fix this? If I can't I will stop using Firefox as I cannot function like this. Please advise!

So I was trying to test webauthn so I went to webauthn.io and then signed up with my username but firefox then tells me touch your security key to continue with webauthn.io but it works very well google chrome. and shows me a qr code and then I scan it in my phone. And after some search I think that the problem is that firefox defaults to use the security key which is a physical device but i don't want to use it I want to get the QR code. Also I tried different websites but got the same problem.

And by the way I use arch linux but I don't think that the problem is with arch as I mentioned before everything worked very well in google chrome.

I have used Firefox since it was Netscape, with an ad blocker if one was available. With version 128 I am seeing many, many, many ads where I used to see almost none. I have blocked popups but that's not as much help as you'd hope. I cannot find anythng like AdBlock+ or U Block. Are these no longer available? No longer recommended? I can tell you that they are sure still needed. Thanks.

FireFox 128.0 (64-bit) is back to being a memory hog until everything slows to a crawl. Some releases were better and some are worse. I like FireFox but I am having a hard time getting my work done. Switching between different items slows to a crawl.

Hello, I have Firefox 128 installed on Window10 Pro v. 22H2 fully up to date. I have LastPass: Free Password Manager extension in my Firefox.

Up until 2 days ago I had an icon on my toolbar for the LastPass extension that I could click after opening Firefox to login to LP. It has worked fine for years. It was that way when I shut down my computer that night. The next morning when I opened FF, that icon was gone. LP still shows in my Add-ons manager as Enabled. To the best of my knowledge, nothing on my comp updated in that time period.

I tried clicking the 'Extensions' button in the FF toolbar, but all it did was to open the "Recommendations" tab of my Add-ons manager. Previously, clicking the 'Extensions' button in my toolbar would show a menu of extensions including LP. I would get an option to show an LP icon in my toolbar. That worked as recently as a few weeks ago when I wiped my hard drive and did a fresh install of Windows.

I tried removing and reinstalling the exension. It made no change. Next I fully removed Firefox with the Remove Programs option in the Windows control panel, then removed all traces of FF in my Windows user profile. Then rebooted. Then DL'ed Firefox fresh from the FF site and re-installed it. Twice. No icon shows up, and the 'Extensions' button continues to do nothing but send me to the 'Recommendations' tab of the add-ons manager.

I had a few other extensions installed as well as LP at the time this problem arose. But when I re-installed Firefox, I only installed LP and tried to get its icon showing before installing any other extensions, just to be sure there was no conflict.

Can you offer any suggestions to help?

Thank you.

I've just created a Mozilla account so that I can sync my customised about:config settings between devices but I'm struggling to get it working. For each setting I have customised that isn't on the default whitelist, I have created a new boolean setting as follows:

'services.sync.prefs.sync.xyz' where xyz is the setting I have customised.

Each of these newly created boolean settings is set to 'true'.

When I 'sign in and sync' on a new device and check about:config, the values of these custom settings is not changed from the default.

Have I missed something in my understanding of the process?

Any advice will be appreciated.
