System hangs while visiting YouTube in Firefox.

Posted

Dear all,

I am having a severe issue using Firefox on Linux. That is when I use the browser to watch YouTube it is almost guaranteed that the entire system will hang, become unresponsive and then require a hard reset.

I'm using Xubuntu 19.04.

The laptop is a ThinkPad T450. It has a standard configuration except that I installed a SSD. I ran a comprehensive self-test using the Lenovo BIOS' testing feature and everything was given the all-clear. I note that the same problem doesn't occur on my preferred WebKit-derived browser which is Vivaldi.

I'm not the only owner of a T450 in my household. Curiously, this other T450 which runs Xubuntu 18.04 (LTS) does not manifest the same issue. This system also uses Firefox as its browser.

I was advised to check the system logfiles. The only mention of anything likely in the logfiles is the xsession-errors file:

(xfce4-panel:1291): xfce4-panel-CRITICAL **: 21:01:45.450: panel-window.c:2245 (panel_window_active_window_geometry_changed): expression 'WNCK_IS_WINDOW (active_window)' failed.

Reference to my post on the Ubuntu forums: https://ubuntuforums.org/showthread.php?t=2426276

I'd greatly value any help to solve this issue. I'm willing to look at other logfiles or send over any additional information that might help diagnose this problem. Anything to help me get back to using my browser of choice!

Kind regards. Thran

WMagicModel,

I tried to restart Firefox into safe mode. Unfortunately, it also crashed whilst trying to perform this. The crash report of that incident was: bp-61e8eb09-4b4b-4817-bc7b-d160a0190919. I also have some more details from the xsession-errors which I shall append at the end of this reply.

The latest crash report before this has ID: bp-c3441f06-f87f-4f0c-a7bb-e43620190917. It is possibly corresponding with the hang mentioned first, though when these happen the system itself hangs (mouse and keyboard unresponsive, any audio will become "stuck" on the last second ad infinitum) and I must do a hard reset. I presume that the Firefox crash reporter would not have had the chance to gather anything on the hang.

Edit: Running Firefox with hardware acceleration disabled still causes this super-hang.

Hi Thran,

Was this something that has always been occurring since you've had it, or an update/upgrade to Firefox?

I noticed allot of crashes in version 69.0 with that report. You could try installing Firefox Nightly which gives you the opportunity to test out the latest features while being a possible remedy to your problem.

WMagicModel,

As far as I remember this hang has been happening. I have been using this laptop since early July. I think more than one major release of FF made its way downstream to Ubuntu in that time.

I have installed Firefox Nightly (v71) by way of a PPA repository. Thus far, it hasn't crashed in the same manner. I'll continue trying it for a week and get back to you if this happens again.

As far as new features go, I can only give hearty approval to the new anti-tracking tools.

Best wishes, Thran
