I am using Firefox in a Linux environment with multiple workstations, where I may be logged into more than one workstation at once. The workstations have an auto-mounted home file system such that my home directory (including my Firefox profile directory) are shared.

Because of this, when I try to launch Firefox on a second workstation, I get an error saying "Firefox is already running but is not responding". I have read the support articles about this issue, and other community support threads, but none of them address this use case.

I wish to use the same profile, so that I still have all my bookmarks and such, and have them continue to stay up-to-date. How can I do so in this environment?

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

Recently upgraded to a new laptop, Thinkpad X1 Carbon 11th gen. Running a Wayland-based WM. OpenGL is working fine everywhere except Firefox. Works fine in Chrome, Blender, glxgears, Steam games. Firefox 121 gives the following error:

[GFX1-]: Failed to compile vertex shader: gpu_cache_update [ERROR webrender::device::gl] Failed to compile vertex shader: gpu_cache_update

When I click on a Firefox menu (File, Edit, View, etc.) or the hamburger menu, or a drop-down menu on a web page, the menu appears. Then, when I move the mouse to hover over the menu, the menu vanishes. If, instead, I hold down the mouse button, I can move over the menu without it disappearing.

I'm using a focus-follows-mouse window manager (VTWM) and I think, somehow, Firefox is getting a focus change message when the mouse moves onto the menu. I think this because of the way the Firefox titlebar flickers from showing it's the active window to the inactive window, then active again, once the menu disappears.

Please advise.

Thanks, Richard

Hello,

I am using the Flatpak Version of Firefox on Manjaro Linux. I have hardware accelerated video playback on Youtube for VP9 but not for H.264 on YouTube and Twitch. I can verify that with intel_gpu_top. My hardware should be capable to do hardware decode. You can see in the provided screenshots, that it should work from the configuration standpoint. Do I missing something here or is this maybe a bug? I can provide any further information if needed.

When I start typing my cursor disappears. It does not reappear until I've clicked a few times or wiggled my mouse a lot. This is quite an inconvenience, and I've tried to find a solution for far too long now. This also does not seem to affect any other application other than Firefox.

I have set both widget.windows.hide_cursor_when_typing=false and hideCursorWhileTyping=false I have also verified that there are no OS-level options set for this behavior, although I feel the above settings should override OS settings.

System details: Firefox 121.0 64-bit Mozilla Firefox for Ubuntu (non-snap) Ubuntu 22.04.3 LTS Gnome 42.9 Experienced on both X11 & Wayland

Please let me know if any additional information is needed

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.

Hello !

I am trying out a Linux (Fedora 39) with enhanced privacy (hardened firefox with the user.js from Arkenfox). My problem is the following : When I quit a video that was in full screen with Esc. the inner window dedicated to the webpage resizes to a smaller one such as the one seen in the screenshot.

I fixed that by going into troubleshoot mode and the window went back to its original size and then reactivated my extensions but the same problem appeared when following the process aforementioned.

Any idea what could be causing this ?

Best regards,

Firefox 120.0 on openSUSE Tumbleweed.

Google Maps (https://www.google.com/maps) results in CPU being pegged at 100%. No other tabs open. All I have to do is load the URL and do nothing else. This behavior is repeatable. CPU stays at 100% until tab is closed or browser is shut down. Sometimes the browser will hang and its PID has to be killed.

Offending process:

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

Thanks.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

here

A friend (who knows even less about technology than me) has an old Dell Inspiron 1501 which has been running Linux Mint 18 Xfce, which is now unsupported. I'm beginning to regret it but just to keep it going for a couple of years I offered to update to Mint 20 Xfce, which is the last version listing 1 Gb as the minimum Ram (everything later or other version are 2 Gb or more), which is the most that system can use. Once the wifi was eventually working (old b43 broadcom driver) most things went fine (except Team Viewer, which works on another Mint 20 Xfce system, but that's not a question for here). However, she uses Yahoo mail, and for some reason just attempting to load the login page (login.yahoo.com) causes Firefox to crash (I mentioned Thunderbird in the title as I attempted to access Yahoo Mail with it, but because it needs to access the Yahoo Mail page (as I think this is now based on App codes rather than passwords), and doing that crashed Thunderbird also). I'm pretty sure I have methodically gone through all the troubleshooting steps on https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems (clear cookies & cache by deleting history; clear startup cache; refresh; reinstall; new profile). Firefox doesn't crash in Troubleshoot mode, despite the fact is seems to still use hardware acceleration, even though I thought it would disable that. Hence, I'm at the end of what I know to try (and that's just from following the guide, I am not an expert) and would be grateful for any help anyone can offer. I attach an image that lists all the submitted crash reports, as they will refer to slightly different conditions as I tried all the options mentioned above. I'm using my own PC to submit this (so any hardware & system data submitted by this web-form won't be relevant), not the Inspiron 1501 that has the issue. I can open the Yahoo mail page on this machine (same version of Firefox) and also on the Inspiron 1501 using Chrome (but there was a different reason relating to security why we couldn't log in via that). Would really like to get Firefox (and Thunderbird) working on the laptop, if possible.

Hello, I have a very odd problem with my firefox browser. I am running firefox 88 64bit on a 16.04 (I know...) Ubuntu. On certain websites, I have an issue with interactive content: www.leboncoin.fr will not let me login anymore (quite recent) www.decathlon.fr will have trouble displaying user comments, images, let alone placing an order Now and then websites with dynamic content and forms will not load...

I am not sure what is the link between all these but it seems related. I have tried the troubleshoot mode but it does not change anything. At the moment when I need to use these king of website I have to switch to another browser.

Thanks in advance for your help!

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.

what triggers the captive portal login... ? It's a great feature on a phone!

I am experiencing it on Linux 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux, Firefox 115.1 (esr?) to 120.0.

Firefox is talking out through a Comcast-supplied router to the outside world and the captive portal attempt is being sent to one of localhost's aliases.

Beginning with 111 when I start I get 'glxtest: failed to read data from glxtest, we may fall back to software rendering.' It works. I don't know that anything bad is happening.

I often see that some pages take up too much memory. This critically affects the performance of my laptop with 8 GB of memory. However, I was unable to reproduce this behaviour. Now I have caught two web pages.

https://linuxhandbook.com/sort-top-command/ 

and https://www.tutorialspoint.com/how-to-find-number-of-ram-slots-in-linux The first page quickly takes up 1-2GB and continues to drain memory. The maximum usage was 7 GB on a laptop with 16 GB of memory. This behaviour is the same in Firefox and Chrome. The second page quickly takes up 2GB, which is very noticeable on 8GB laptops. Why do these pages take up so much memory? Most importantly, how can you protect yourself from such an unexpected memory consumption?

Hi, I seem to have an issue with Firefox rendering pages with artifacts. I use Linux Mint 21.2 Cinnamon, video adapter is Intel HD 4000. Currently running 6.2 kernel, tried to fall back to 5.15 which didn't change anything. Attached the examples, the first 2 are screenshots of the about:support page, the issue appear there consistently but not necessarily at the same place. I've tried to open Firefox in the Troubleshooting mode, and the artifact appeared right in the dialog asking for restart! (see pic. 3) Enabling software WebRender (gfx.webrender.software=true) fixes the issue.

I have tested memory with memtest86+ overnight with no errors, CPU has been tested by Prime95 for 3-4 hours, the iGPU seems to be working fine either in Unigine Heaven, GpuTest and glmark tests. Is there a way to fix the issue other than disabling HW compositing?

Hello!

When trying to load specific profiles, Firefox freezes and my system blocks, with fan on full speed.

I have to either kill that profile via process manager (before everything freezes) or force shutdown my computer.

The only thing these profiles have in common is that their names have special characters ('í' and 'ã'). Renaming has no effect but Firefox being unable to find them.

Unfortunately I have no error message to quote. I need to use these profiles because of their specific saved logins data.

I'm on Debian GNU/Linux 12 (bookworm) x86_64, 6.1.0-12-amd64. Firefox verson is 115.4.0esr (64-bit).

Thank you for your time. -chico
