Firefox+Plasma often freeze up


I want help on how to troubleshoot an issue. The issue is that sometimes Firefox randomly freezes and stays that way unless I restart the PC (which takes a lot of time when this happens). Only FIrefox gets frozen not the entire system, although in the past it used to take Signal with it.

I don’t have a clear picture of patterns that may cause it, since it has happen in several different senarios. My initial guesses is that something is wrong with Firefox or with Plasma.

Since I am not very experienced and I can’t think of a way to replicate it, how do you think I should track this down? Which logs to check?



Welcome to the forum! :slight_smile:

There could be tons of reasons for that, but we won’t be able to help you unless you provide us with more information.

  • First of all, have you updated your system yet?
sudo pacman-mirrors -f 5 && sudo pacman -Syyu
  • Secondly, we need information about your hardware. Please post the output of…

Well, I have experienced Firefox 79 and 80 to frequently hang under Manjaro/GNOME but also under Windows 10! Whenever some control widgets are on a page (like in Google Drive Apps) chances are high it stalls to zero. It will eventually recover, can take longer than 10min!!

Hi, @SuAlfons,
Did you install the plasma integration add-on on firefox?
Maybe, it could be the solution for this problem.


I will try these out next time, thanks!

I have updated today yes.

Sorry for not providing them already (I thought you might want them), it’s just that I want to understand the thought process of troubleshooting manjaro other than just the solution.

I had a similar issue (black screen seemingly randomly, never recovered though) although closing out of Firefox, and opening it again resolved - until it happened again.

The suggestion Tomek linked seems to have done the trick for me! Hope you have similar success Chuhtra.

Truth be told I haven’t had a similar problem since I posted here.

Although I had twice a total system freeze when being in a Jitsi call through Firefox and trying to share screen. But since it was a total freeze I could think of nothing else than going in tty and rebooting (since tty+change session wouldn’t help)

Good to hear that you solved it so easily!
