Details

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

  1. Start Firefox Firefox v 94.0+linuxmint1+uma on a PC running LinuxMint v 20.2 (Cinnamon)
  2. Goto https://www.3blue1brown.com/
  3. Click on 'By Date' and then play 'How a Mandelbrot set arises from Newton's work'.

Actual results:

After playing the video for about 50s, the tab crashes with the message:
"Gah. Your tab just crashed.
We can help!
Choose Restore This Tab to reload the page.
Close Tab Reload Tab"

This happens on two PCs running LM20.2.

Expected results:

The video should play to completion without errors (as it does in Firefox 94.1 in Windows 10 Home 21H1 OS Build 19043.1237).

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Thanks a lot for reporting the bug!

Could you please help us investigate the crash by following instructions on [1] to identify the crash, see if the report has been submitted, and provide the report ID here? Thanks a lot.

Followed ref [1], and entered about: crashes - got the message:

This application has not been configured to display crash reports. The preference breakpad.reportURL must be set.

This meant nothing to me! So, looked in ~/.mozilla/firefox/Crash Reports/submitted and found a single txt file, dated Sun 07 Nov 17:02 GMT, with a single line:

Crash ID: bp-1ebfe300-87fc-459f-880d-5e7fd0211107

Hope this helps...
Note: there are later (unsubmitted) crash reports for 7th and 8th Nov which probably relate to this issue, in folder ~/.mozilla/firefox/Crash Reports/pending . If these might be useful, I can send them, if I'm told how to.

Thanks for those crash ids. This looks similar to bug 1715975 (and bug 1514734, bug 1739924).

:jld, is there a bug you'd like to dupe and consolidate against for these, or is it useful to track separate cases?

The discussion seems to have converged on bug 1739924 (and https://bugzilla.redhat.com/show_bug.cgi?id=2020981, downstream at Red Hat). Current status is that it looks like file descriptor exhaustion, possibly connected to using EGL for graphics, and we're waiting for someone to reproduce it and use lsof to see what fds are being leaked.

Have just downloaded Firefox v 94.0.2 from
http://ftp.mozilla.org/pub/firefox/releases/94.0.2/linux-x86_64/en-GB/firefox-94.0.2.tar.bz2
It seems to play the entire 3blue1brown video ok.
