> Just hit this on https://redhatuniversity.adobeconnect.com, using an up-to-date Fedora 29, and it's reproducible for me... more specifically, I can listen in to group meetings on https://redhatuniversity.adobeconnect.com and as soon as I click on an any icon or text box in that flash based UI it crashes.
> as soon as I click on an any icon or text box in that flash based UI it crashes. this was in a Wayland session. When I logout and start a GNOME X11 session then it's fine! Perhaps this is useful information to anyone debugging this.
Me too: - up-to-date Fedora 29 - firefox-66.0-6.fc29.x86_64 - X, not wayland "Reporting is disabled because the generated backtrace has low informational value"
Just noticed this in the journalctl output: Jun 24 17:39:22 dima-dell gnome-shell[1754]: WL: error in client communication (pid 3214) Jun 24 17:39:22 dima-dell gnome-shell[1754]: clutter_actor_get_parent: assertion 'CLUTTER_IS_ACTOR (self)' failed Jun 24 17:39:22 dima-dell gnome-shell[1754]: clutter_actor_remove_child: assertion 'CLUTTER_IS_ACTOR (self)' failed Jun 24 17:39:22 dima-dell firefox[3214]: Lost connection to Wayland compositor.

[Child][MessageChannel] Error: (msgtype=0x250016,name=PCameras::Msg_AllDone) Channel error: cannot send/recv Jun 24 17:39:22 dima-dell audit[3680]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=2 pid=3680 comm=43616D6572617320495043 exe="/usr/lib64/firefox/firefox" sig=11 res=1 So the Gnome Shell is disconnecting Firefox due to some error. Firefox's stack trace is probably not even going to be useful, since it's all async. Need to find out the "error in client communication" might be.
This might actually be a bug in the Wayland server library - or at least a limitation. Every time I got this crash, Firefox would freeze for 10+ seconds before the crash happened - did this happen to everyone else? I was assuming the freezing was part of crashing - Firefox generating a stack trace or whatnot. But now I have a different hypothesis: Wayland server appears to disconnect unresponsive clients fairly quickly. It's done by the wayland library itself, and Gnome doesn't even get a change to show the "this app is unresponsive" dialog box. So Firefox could freeze for some time for a completely unrelated reason, and get killed as soon as it unfreezes. Here's a way to reproduce what I'm talking about using e.g. gedit: 1. Start gedit, and freeze it for 30 seconds: gedit & pid=$!; sleep 3; kill -STOP $pid; sleep 30; kill -CONT $pid 2. Move the mouse around the window, click it, etc. - I think this is important 3. Wait until it's unfrozen. It will likely get killed right away. It would be nice to find out why Firefox freezes - but that shouldn't justify the compositor killing it.
I caught it in the act: I was trying to close a tab by clicking "x", and Firefox froze. I quickly attached GDB before it crashed for real. I wasn't even able to get a full stacktrace - GDB and Firefox were using up all of my memory - but here's whatever I was able to see.

Can you please try latest nightly binary provided by mozilla? How-to is here: https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries Thanks.
I've upgraded to FF 68 a few weeks ago, and haven't had a crash since... It's looking promising.
Hello, abrt reported bugs come from various sources/scenarios and usually can't be reproduced. This is automated bug processing which is applied to all abrt reported bugs which are supposed to be non-reproducible. If you can reproduce the bug (you have a testcase), please reopen it and assign it directly to me - stransky. Thanks.
