Firefox/Gnome/Freeze/Crash

Just installed Arch linux for the first time (with Gnome DE) on my Dell Latitude E6230 (128GB SSD, 8GB RAM + 8GB swap partition + 4GB swapfile).
When i am using firefox (only when using firefox, other browsers/apps does not cause this bug) for a few hours my browser freezes for a while (like 10-15 seconds). I never open more then 6 tabs at the same time, so this should not be a problem. 1 out of 5 times when my browser hangs I also get logged out from my user account.
I am pretty sure this bug is related to some kind of memory problem but i am not sure why. My swap partition is encrypted (LVM, so is my /home and /root (~30GB) partition), this could be a reason but I never had any problem with encrypted swap partitions on other distros so I have no idea how to solve this kind of problem.

Any help would be appreciated!

Re: Firefox/Gnome/Freeze/Crash

Please wrap output in [ code ] tags.

Reads like some compatibility problem with XWayland, to rule that out, can you try in a Xorg session? Choose "Gnome on Xorg" in GDM if you use that.

Re: Firefox/Gnome/Freeze/Crash

Thanks for pointing out the code tags, I totally forgot those!

So I tried the Gnome on Xorg option, fired up firefox and I opened 8 tabs to speed up process (including some heavy ones like fb and yt).
After like 1-2 minutes firefox got frozen once again. I was using the System Monitor and found out that memory usage was at 40-45% the whole time but CPU4 was at 100% when the hang of firefox occured. Firefox went half way transparent (as I was maximizing the window when the hang occured). As soon as firefox got back to working my CPU went back to 15-20%. Checked journalctl, it didnt show anything suspicios this time.

Re: Firefox/Gnome/Freeze/Crash

I have two additional things you might check, one is making sure that your microcode updates are properly applied https://wiki.archlinux.org/index.php/Microcode

The other is that there were a few threads lately that mentioned issues with swap on LVM, llok at https://bbs.archlinux.org/viewtopic.php?id=231083 for more info

Re: Firefox/Gnome/Freeze/Crash

Thanks for the advice!
I managed to work around this issue by setting firefox multiprocessing to false in about:config.
Since I did that the hangs and crashes disappeared.

Re: Firefox/Gnome/Freeze/Crash

I have the same issues. Very sad about it.
