Description Vít Ondruch 2020-03-31 12:45:15 UTC 
Description of problem:
Recently, FF is crashing for me a lot, especially during video conferences via BlueJeans. Here are the recent crash reports from my system.

This is the first batch crashing in `moz_container_get_wl_surface`

https://crash-stats.mozilla.org/report/index/00256d82-9749-404d-9f59-bb0f30200331

https://crash-stats.mozilla.org/report/index/cb302cc9-2263-4f75-816e-3606e0200331

and this is the other crasing in `wl_proxy_marshal_array_constructor_versioned` which I would be surprised if it is very different.

Version-Release number of selected component (if applicable):
$ rpm -q firefox
firefox-74.0-11.fc33.x86_64



How reproducible:
Sometimes, especially during video conf right after I ask some question ;)


Steps to Reproduce:
1.
2.
3.

Actual results:
FF is crashing.


Expected results:
FF works.


Additional info:
Also, it is quite annoying that the crash reported stays open and the "restart firefox" does not work well, because the newly started FF instance cannot access the web cam and mic, because the crash reported keeps them locked.

Thanks for your report. This looks like https://bugzilla.mozilla.org/show_bug.cgi?id=1624745 which is fixed in upcoming Firefox 75.
Comment 2 Vít Ondruch 2020-04-01 09:05:06 UTC 
Thx for the pointer. It would be nice to have this patch included in Fedora, because it is very annoying bug.

In the mean time, here is scratch build with the patch applied:

https://koji.fedoraproject.org/koji/taskinfo?taskID=42941453

I have updated my FF and will see during my afternoon meetings.
Comment 3 Martin Stransky 2020-04-01 10:24:52 UTC 
Yes. There are already 75 candidates available so I'll do the new builds asap.
Comment 4 Vít Ondruch 2020-04-01 12:25:02 UTC 
Thx.

BTW two meetings later and without crash, so far so good :) Appreciate your effort.
Comment 5 Martin Stransky 2020-04-06 12:09:21 UTC 
Added to firefox-74.0.1.
