Hello

Recently I've upgraded from Kubuntu 24.04 to 24.10. I'm almost sure that the minimize/restore buttons were available in my Firefox after the system upgrade. For the last few days I can see they are missing - please see attached images.

I can partly fix the problem by going to Settings->More tools -> Customize toolbar and selecting "Title Bar" checkbox. In that case I have the title bar displayed with all 3 button (minimize, restore, close).

But I would like to have the default behavior: title bar is turned off and the mentioned 3 buttons be visible in the tab bar.

How to have those buttons in the tab bar when the title bar is turned off?

Hello everyone, i have Linux/Ubuntu software with Firefox browser and for 5 months it has not asked me to update, with it's pop up message. Now it is urgently asking me to update, i have followed the directions given in order to download the latest Firefox version as instructed but with no success. I am downloading it, but it doesn't have an instruction to "run" it. As a consequence, my system is getting slower and slower and i am afraid it will crush! Any ideas? Sooooos!!!

Hi, after upgrade of ubuntu to 24.04 i got into problems with using Firefox. I it running on x11 with proprietary nvidia driver, no matter of source package (snap or deb from the Firefox repository) and no matter of safe mode the Firefox gets frozen when clicking into any dropdown control in side page, the same happens when trying to open bookmark folder in the bookmarks panel or even the dialog that opens from the star icon in address folder that should add page into the bookmarks. When running on command line, in case of the snap version there are just some warnings of some missing css file, in case of the deb version it does not output anything suspicious. I was even trying to change the UI theme (qt) as well as GTK theme in case it makes any difference, but it did not... Thanks for any help.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Browsing works well on my Ubuntu/Linux 22.04.5 laptop except one site. Images are not loading. I can see it has js-errors which might be related. And that may be because some js files are being blocked. The site does work on my iphone though. And using Browserstack I can see it works with other OS.

The site is: knowledgecottonapparel . com

I've verified that others using Linux has the same issue, https://askubuntu.com/questions/1526728/issue-with-specific-site

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

Hello, Firefox friends!

I'm having some issues with Firefox on my Ubuntu system and I'm really hoping someone can help me fix them.

   Problem with Downloads: When I try to download something and click on a link, a new tab opens. But then it immediately closes and nothing downloads.

   Button Issues: Some buttons within Firefox just don't seem to work.

I've tried a few things already:

   Checked for Firefox and Ubuntu updates
   Ran Firefox in Troubleshoot Mode
   No antivirus because I'm on Ubuntu

If anyone has faced similar issues or knows how to fix this, please help!

Thank you so much!

When browning some site will cause a Firefox to freeze, all UI stops working, if I try and reload the page nothing will load and if I try and close and reopen Firefox I get a zombie process that last for about a minute. Obviously this is with no ad dons or hardware acceleration and nothing is listed at about:crashes. The only useful tip I have comes from the command prompt. First when the freeze is first triggered I get the errors ``` MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen ``` and when I try and open it after a freeze and there is still a zombie Processes ``` [Parent 111218, IPC I/O Parent] WARNING: process 111455 exited on signal 15: file /build/firefox-RH6krf/firefox-115.0+build2/ipc/chromium/src/base/process_util_posix.cc:264

``` and finally when it kills the zombie processes ``` RunWatchdog: Mainthread nested event loops during hang:

--- CanvasManagerParent::Shutdown

ExceptionHandler::GenerateDump cloned child 111871 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... ``` the included images are what pops up when trying to open Firefox when it still has a zombie processes and when it kills the process

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

Hi, I have noticed that when using the latest release of Mozilla Firefox on Windows 10 and Ubuntu 22.04 LTS, when I go to ABCnews.go.com and click into a story, there is an autostarting video. But instead of either waiting until I click on it or autostarting normally, it flashes wildly. I have disabled all extensions and the problem persists. Has anyone else encountered this? And more importantly, does anyone have a fix for this issue?

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.

YouTube keeps putting up the add block detection when I try to play a video. Apparently they can detect Add block Plus. Kubuntu 24.04 Firefox version 130.0 [64-bit] Mozilla Firefox Snap for Ubuntu Canonical-002-10. Add block Plus version sorry I can't find that information.

Firefox does not seem to be properly configured for Wayland on KDE Plasma 6.x systems. The generic "Wayland" logo appears in task switcher instead of the Firefox logo. Firefox is the only program I have with this issue. Setting desktop name (org.mozilla.firefox) as a property in the Window and Application Manager settings does not resolve the issue.

I upgraded Firefox using Ubuntu's apt update, apt dist-upgrade. The upgrade process said my version is 134.0.1 but when I look on the Help button is says my version is 125.0.2. How do I upgrade to 134.0.1?

Hi, I've been struggling with this for months and can't find an easy solution or a good explanation. I'm running Ubuntu 22.04 pretty basic, I don't have many custom repositories enabled or anything, just a few additional packages like slack, Teams or Chrome. Ubuntu switched Firefox to snaps as well, and I can't get internet access with it. The error message is:

--- May 12 12:16:20 nuc kernel: [12948.381392] audit: type=1400 audit(1683886580.562:131): apparmor="DENIED" operation="open" profile="snap.firefox.firefox" name="/etc/fstab" pid=7731 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 May 12 12:15:43 nuc rtkit-daemon[1030]: message repeated 3 times: [ Supervising 10 threads of 4 processes of 1 users.] May 12 12:16:20 nuc dbus-daemon[790]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.175' (uid=1000 pid=7731 comm="/snap/firefox/2645/usr/lib/firefox/firefox " label="snap.firefox.firefox (enforce)") ---

Simply stopping (and aa-teardown) doesn't work at all, Firefox doesn't even start without apparmor running. I'm not an expert with apparmor, but I wanted to set in complain mode instead enforce, but I'm struggling with that, too. I didn't touch the /etc/hosts file, the error message is a little different on another Ubuntu 22.04 computer I use, there it complains about permission denied for the resolve.conf. So I'm asking the community, how do you deal with this? Searching the web gives me all kinds of ideas, but none of them work. Could anyone help me out here?

Thanks!
