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.

(/usr/lib/firefox/firefox:1631): dconf-WARNING **: 21:01:47.129: Unable to open /var/lib/snapd/desktop/dconf/profile/user: Permission denied [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 </p>

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
