I run Firefox under Linux Mint. Both are always update to the latest level. Over the past 1 to 1.5 years, across updates to both Firefox and Mint and multiple 'clean' installs of Firefox, I have experienced many crashes from Firefox per week. Sometimes there will be as many as 5 per day, but never less than one per day. During the same period I have also been running Vivaldi; it has not crashed once in that time. Now I have to do something. If there is a simple way to perform 'problem source identification', that is within my capability, I would be grateful for advice. If there is not, then clearly I will have to un-install Firefox.

As far as I can tell both of these browsers run with just 1 add-on/extension: uBlock Origin. Disabling this extension in Firefox does not stop Firefox from crashing.

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

After updating FF to v. 136.0 in Linux Mint 22.04, I noticed a problem with video playback in Facebook in some posts. A black screen appears with the message "Sorry, there were problems playing this video". The problem also occurs after disabling all plugins and deleting the user.js file from the profile. The problem does not occur after starting firefox in troubleshoot mode, but then hardware acceleration using the GPU does not work (Compositing: WebRender (Software)). I noticed that in version 136 there were some significant changes in the topic of video decoding. https://www.phoronix.com/forums/forum/software/desktop-linux/1524008-firefox-136-beta-finally-enables-hardware-video-decoding-for-amd-gpus-on-linux-by-default I have an NVIDIA GT1030 GPU with 2 MB VRAM.

I use tiling for my windows. After minimizing and then restoring the windows, the tab bar is no longer displayed. If I don't tile the windows, this error doesn't occur. I'm using the latest version of Mint Cinnamon. This error also occurred in debug mode.

$ wmctrl -m Name: Mutter (Muffin) Class: N/A PID: N/A Window manager's "showing the desktop" mode: OFF

In general Firefox is working. However, after every update, both major as well as point releases, where Firefox updates and then restarts itself, it almost always starts up and displays the homepage (local page on my machine) but is completely unresponsive. It will not load a locale or a remote page. I can kill all running firefox processes and then manually restart the browser -- with the same behavior. I have discovered that if I wait for around 10 minutes or so, then the browser starts working and continues to work just fine until the next update. Once past this initial update wait, I can kill/restart the browser, reboot, etc. and Firefox is responsive. It is only immediately after the updates that this problem occurs. This has been going on for at least the past six months or so, but is new behavior that didn't exist prior to that. This isn't a show-stopper, but it is very frustrating.

Any suggestions.

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

Hi there,

I'm experiencing a theming issue when using Firefox (flatpak) on Hyprland with a pure black (#000000) theme applied via a theme extension. When the Firefox window is out of focus, everything looks fine — the background is truly black as expected. However, when the focus is on the window, the blacks turn washed out grey, losing the #000000 appearance. This doesn't seem to happen in other apps and I don't seem to have any filter for the focused windows (except for borders), so it seems related to how focused windows are handled in Hyprland or how Firefox draws its content under Wayland - have you heard about this issue and could you help me diagnose it + find a solution? Is there a setting I could tweak either in Hyprland, Firefox, or GTK/Qt config to prevent this color shift on focus? Thanks in advance!

It says on https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts that the hotkey to toggle `PiP is CTRL Shift ]`. When I play a video it shows the PiP button, but the hotkey doesn't work. The other PiP keys like seeking and volume work. I'm on Fedora 41 with KDE 6.3.3 & Wayland.

After the last Linux upgrade to 36.0.2 the password or user name hot links only work once. The first time the link is gray and will activate. The second time I try and use this feature the link is not gray and will not activate.

Every time this happens I have to close Firefox and reopen it. Then I get one more shot at auto loading a password before it stops working.

Is there a way to just paste a file with path for uploading. In the windows dialogue I can do that to bypass waiting, but in the linux dialogue 1. I really have to wait for all folder content to be shown (I just tried that on a network drive with a quarter million images) 2. I cannot just type paths that are hidden but I know they exist

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

I updated firefox just yesterday or earlier today idk and the right click menu is so long with multiples of the same and they DO NoThInG! Linux Mint 22 Cin. 6.8.0-55 Generic Kernel

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.
