Firefox crashes

I have a small problem:
when I download a file (e.g. systemrescuecd or other) and I open the download manager,
then Firefox crashes.

This problem does not occur, when I use a new .mozilla folder with copied bookmarks

key4.db= has to do with passwords, I don’t remember exactly, but worth backing up
logins.json = saved passwords
prefs.js- self explanatory
search.json.mozlz4= Search engines, including custom)

How can I track down the problem?
This occurs, when I have listened to internet radio (

I don’t know, but when you have a problem with Firefox, if you can’t figure it out quickly, just refresh the profile and be done with it (you need to configure Firefox settings again, get your add-ons, themes, but everything else is kept). It could be so many things, check terminal when it happens (obviously open Firefox from terminal).

//EDIT: Firefox is broken. I got the same problem. Will check it later.

Isn’t that related with the latest ‘libx11’ update?
The 1.8.2 version kind of mess with Firefox.
Can you check the version, please?

No need to check, I’m on the version currently in Manjaro, as we all are. Can’t find proper repro yet. Starting from terminal I always have no output showing in the terminal, when the download manager window opens, it hangs, it never shows content, and closing it leads to KDE asking to wait or close firefox process.

If coredumpctl, or if you turn them off, journalctl -b -g core-dump --no-pager -o short-unix shows related output that could explain the slow shutdown, but not the root cause.

Just some thoughts, could try:

  • Turn off hardware acceleration if on, or
  • ctrl+shift+del to clear cache, offsite data…follow dialog as needed
    Alternatively use firefox menu > Settings and search for cache to get positioned and follow dialog
  • firefox’s about:about has some useful tools/data; see if any apply (i.e.: about:crashes)
  • Search bugzilla.mozilla for the messages you are seeing on the console or problem.

I am using Firefox 108.0.

How can I check libx11 version ?

Arch just updated libx11 with some patches to fix crashing on Firefox:

Im also experienced today my first Firefox crash under Linux. Or better to say, my window was freezing and inside of the window it copied the desktop after it was minimized.

But its sporadic… it crashed with 108.0 after using Firefox for around 24hours.

Anyways, no crash showed up in journal. I had to force close the firefox window.

libx11 is version 1.8.2-2.

Indeed, can’t find relevant errors. I also had sporadic random Firefox weirdness, in the past month, for example sometimes when I have multiple tabs opened, after some random event not yet discovered, it is like Firefox is frozen, you can not switch tabs, but if you right click a tab, it instantly shows it, but the content does not refresh, but playing with the right click on tabs properly show the tab, this is weird, and so sporadic I didn’t bother, but this all can be linked, maybe the update of libx11-1.8.3-3 that is on Testing now, will fix that, I’m updating right now, will update thread later tonight after doing more tests with the download manager window.

//EDIT: so far, I can’t reproduce the thread’s issue, will see if my (related?) issue is fixed too. So far so goo on my side on Testing branch.

I have never experienced this issue. I am running Nightly as my main browser, updated daily, straight form Mozilla on xfce unstable. I hope it is fixed for you folks. On a side note, I had an issue with some nightly builds, last week, with the dropdown bookmark icon on taskbar where when hovering over on “Other Bookmarks” it would collapse instead of cascading to the right and no other bookmarks could be seen. I reported the bug and it was fixed within two days.

After the last update libx11 is now at version 1.8.3-3.

Firefox at version 108.0.1.

Now, the Firefox crashes are gone.

Yep I didn’t have issue since the update of libx11

My (related?) issue was back today, but I guess it may not be related then

It appears that the latest firefox 109.0 is fixed. I use it with hardware acceleration enabled and i do not see it crashing. As expected, firefox is much faster and more agile with acceleration enabled. I use Manjaro Linux 22.0.0 Sikaris, Kernel 6.1.1-1, everything fully updated, no updates are available for my computer. Firefox runs two instances, one instance runs netflix and youtube, the other runs Facebook, LinkedIn and Manjaro forums at the same time and it works for me. People, please check and test if your can confirm the issue is gone, or if you still have it.

The issue was fixed one month ago in libx11.
