Firefox keeps completely freezing randomly

Disabling hardware acceleration seems to have actually fixed it. But the question remains: How did this get broken if neither Firefox version, nvidia driver version nor kernel version seem to be the cause?

I don’t do Nvidia (quite by design) but I believe if you have the proprietary Nvidia driver installed you are not using Mesa as such? If I’m mistaken about that: mesa was upgraded so that could presumably be related.

How do you turn this off??

I just uninstalled all of Firefox and then searched and delete all files and folders for Firefox, both on System/boot and home folder, rebooted and reinstalled Firefox, then synced (Firefox Sync)my stuff, and it still crashes/freezes with download dialog window and now I’ve gotta setup all the websites that need Logging in :pensive:

Oof, always do backups before drastic measures!

Go to Settings β†’ General, then scroll to performance. Uncheck β€œUse recommended performance settings” if checked, then uncheck the hardware acceleration checkbox that appears (if checked)

Just found it and am now about to test, fingers crossed.

It seems to be working, just downloaded stuff left right and centre and so far no crash/freeze when opening Download dialog window.

I’m not sure if its me but Firefox seems to be running smoother with hardware acceleration off?, Checked HQ Videos on YouTube and all played back perfect.

It could be because as i said i uninstalled Firefox and delete all Firefox Folders and Files.

To be perfectly honest I’ve also had the idea that disabling hardware acceleration in Firefox doesn’t in fact feel detrimental – but, well, it likely is in specific situation.

Are you also on Nvidia? If so this might be Nvidia specific I guess. I as said don’t have the Downloads issue/trigger available on (very) old Intel integrated graphics.

Yes RTX2060 and driver 520.56.06.

If you’re curious or feel socially inclined towards other users I guess you could try and see whether or not switching to the open-source β€œnouveau” driver allows to re-enable Firefox’ hardware accel.

No, But i do have 2 Laptops, with AMD K8/Radeon, and AMD Ryzen/Vega, I’ll update them at some point and see if it happens on them.

OK. For someone else possibly interested in testing nvidia/nouveau difference: it seem you can on Manjaro do so easily as per How do I switch between Nvidia and Nouveau drivers on boot? - #4 by stephane

Still would like to know how or why this is happening as it was working fine before today’s update?

I’ve also been having this issue, with firefox freezing at first and then seemingly all of GDM until I switch to a different terminal and restart GDM. I just turned off HW accel and am hoping it helps for the time being.
(I’m on a laptop with a RTX3070 mobile gpu.)


Firefox 107.0 did not fix the problem, Still need to turn off performance and hardware acceleration.

i’ve uptate to 107.0 and no freeze after many hours of using ff .
You can use mozregression to verify .
β€œmozregression --find-fix --repo=mozilla-release --good 107 --bad 106.0.5”

in my case problem solved .

I have a similar problem about firefox in the KDE. Suddenly, ff got freezed. In fact, the title bar, therefore the closed button, of ff disappears. In fact, the title bar of other applications also disappear. Moreover, the panel of kde also disappears and I can’t change to other applications by shift+tab.

I don’t know wether this is a KDE problem or a ff problem. But it seems very similar to the bugs discussed in this topic.

Nope, still immediately freezes after trying to open the Downloads window.

Hi, I’m also having the same issue. I’ve tried downgrading firefox from 107 down all the way to 105, and it still froze from time to time. I’ve also tried changing kernels and disabling hardware acceleration to no avail.

For me the freeze didn’t happened when opening the download page, but when copping text either from firefox or to firefox.


I’m also experiencing sporadic freezing issues again as well. For me, the issue is on-again, off-again for weeks now after experimenting with different acceleration options. Some problem correlations are multi-monitors, video streaming, and problems when attempting to open (or switching to) new tabs or instances. Can anyone please post any recent core dumps from journalctl? I still don’t have any items in about:crashes. Maybe (if not hw-related), explore UI/theming issues again?

I’ve problem with Firefox
Its non functional after latest update.
I could tray reinstalling, starting with debugger mode and so on but unfortunately couldn`t get any visual piece of Firefox. Its looks like frezed window contain noting. Catches other window’s visuals. Can be related X11 maybe. Because its renders nothing.

firefox --version
Mozilla Firefox 107.0

I couldn’t manage to get coredump file from gdb which I applied these steps.

coredumpctl list|grep firefox
coredumpctl list|grep 1116

Just I`ve following…

cat /proc/1116/cmdline 

Could you clarify more, how can I get it? Because I’ve also problem with firefox
