User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0

Steps to reproduce:

Today after upgrading to 89.0 version, after certain time of usage my browser becomes frozen and doesn't respond to any click, it happened 5 times today, task manager shows no memory leak, the only solution is to kill it. This never happened with previous version which I used almost everyday without problems.

We've got similar reports about SW-WR on Wayland and I suspected the Wayland software backend to be at fault. However that was not confirmed yet (see bug 1694038 comment 11). One suspicion is that it has to do with us running out of RAM and not handling that well, see bug 1694038 comment 15.

Summary: Firefox freezes and becomes unresponsive → [SW-WR/X11] Firefox freezes and becomes unresponsive

In my case I have free RAM and the CPU is only running at 50% and other programs are running fine, but whole Firefox interface is frozen.

KDE Plasma Version: 5.21.5

KDE 5.22 will have more Wayland Fixes so let's wait to it. Also we'd need to to tests on Gnome/Mutter to compare those two environments.

The bug reporter specified X11 though.

Graphics Platform: X11

I see, sorry for the confusion.

This problem becomes truly severe for me, it always happens and all my work (live sessions) and entered texts are lost ! This should be high priority, I don't know why but previous version never get frozen, and also chromium and brave browsers are working fine on the same machine. Why our favorite browser got destroyed with this new update ! We don't need this new useless interface please bring back our loved stable browser, please.

That indeed sounds pretty bad - you should be able to work around the issue by going to about:config and setting gfx.webrender.force-disabled to true until we figured out what's happening.

For anyone running into this issue: it would also be very interesting if the freezes happen if you activate gfx.webrender.software.opengl. That will make us use a code path that's used on older Android devices and thus has better testing.

I am experiencing a similar problem 1. To be "sure" that is the same problem, does command
$ kwin_x11 --replace &
unfreezes your Firefox?

I am experiencing a similar problem 1. To be "sure" that is the same problem, does command
$ kwin_x11 --replace &
unfreezes your Firefox?

Running "kwin_x11 --replace &" does nothing, Firefox remains totally frozen.
I tried to restrict the range of source problems and run many tests, so what I found is that Firefox becomes frozen in most cases when videos are playing on Facebook or Reddit or any other site with videos then you start scrolling or jumping from tab to another, it does not happen in a fixed scenario but randomly. And it can also happen also on websites without any videos.

I'm following this bug, too. Since v89 it's hanging a few times a day, which is super annoying. Using KDE on Debian Bullseye. The kwin_x11 --replace-trick didn't work out for me, too. I have to kill and restart.

Any idea what to do and how to offer more information? I can't use the browser this way.

It's usually freezing during video meetings or video playback, but maybe just because this causes high load on the browser?

Hi Otto, first of all could you please go to about:support, click "copy text to clipboard", and attach the text to this bug. Then could try setting gfx.webrender.software.opengl to true in about:config, restart firefox, and see if that helps. Please let us know whether it does or doesn't.

If that does not help, then please set gfx.webrender.force-disabled to true, restart, and that should solve the issue while we figure out what the cause is.

Attached file about-support

Hi, i have the same problem in Debian Bullseye xfce, im attaching my about:suppot info here.
I set gfx.webrender.software.opengl to true and testing it right now, i will inform if it works.

I set gfx.webrender.software.opengl to true and testing it right now, i will inform if it works.

Did not work, still freezes. I will set gfx.webrender.force-disabled to true then.

I'm also getting this issue since the aforementioned Firefox version. Disabling hardware acceleration helps. Setting gfx.webrender.software.opengl to true does not help (HW accel. on). Setting gfx.webrender.force-disabled to false helps (HW accel. on). I'm only able to trigger this issue on my desktop PC. Laptop still uses Windows 7 and seems unaffected.

I was able to figure out a reliable way to make it hang on my system:

  1. Open 'https://www.bitstamp.net/market/tradeview/'. This opens a page with a TradeView element. It's not just TradeView that makes Firefox freeze but I found this key into triggering it sooner.
  2. Open a second tab with any other website.
  3. Maximize the Firefox window. I found that the smaller the window, the less likely it freezes.
  4. Constantly switch between the tabs manually with your mouse (ctrl+tab does not work), but while on the TradeView page, hover your mouse over the TradeView element first before switching again. Do this until Firefox freezes. Can take anywhere from 1 switch up to 30; it's pretty random but a freeze is guaranteed if your environment is affected.

I was able to reproduce the freeze with the steps from comment 20 on a newly created profile although it took MANY tries.
It also seems that simply browsing the web with that page running in the background increases the chances of freezing.

Firefox still freezes in 89.0.1 without gfx.webrender.force-disabled set to true

I confirm with 89.0.1 the problem is still persistent, is there any way to revert to 88 and ditch this garbage version (sorry for the word but v89 introduced very high blocking bug) ? For now, it's risky to do any work or sensitive operation on it.

Hi, didn't face the issue a few days, just coming back here.

My status: I just asked what I could do before.
Will attach my about:support info.
And will try to set gfx.webrender.software.opengl = true in about:config now.

Can anyone who's experiencing theses issues try getting a profile with the "Firefox Graphics" preset using https://profiler.firefox.com/?

Jeff, what do you mean with "Firefox Graphics"? Is that some switch at profiler? I don't see such option there.

Flags: needinfo?(jmuizelaar)

Yep. If you click on the drop down beside the profiler icon in the toolbar a settings menu pops up. You can choose "Firefox Graphics" there.

limeclipse, your issue seems different than what some people are seeing here. I've filed bug 1717209 to track it.

It's impossible to click on "Profile" button to stop profiling after Firefox became frozen, is there any external tool to profile Firefox and save the result even if the browser is frozen ?

setting gfx.webrender.software.opengl = true didn't help, Firefox keeps freezing.

I also don't really understand how this profiler is supposed to work. Just launching it during normal operation makes Firefox laggy (not frozen as in the issue, but immediately slow so I have to wait about 10 seconds after every input until I see a tab change, scroll etc). So this doesn't work to reproduce the issue, since normal operation until it's frozen is not really possible.
When the freeze happens, I tried using ctrl + shift + 1, but I don't know if anything useful happened.

For now with 89.0.2 I see no more freezing on Manjaro KDE. I will try to do more heavy tasks and report back.
