Description of problem: Surprisingly Firefox 93 worked fine. I understand it may be a bug of ffmpeg-libs which comes from rpmfusion. I haven't yet tried to really debug it. Version-Release number of selected component (if applicable): FAIL: firefox-94.0-2.fc35 FAIL: firefox-94.0-1.fc35 PASS: firefox-93.0-2.fc35 FAIL: ffmpeg-libs-4.4.1-1.fc35.x86_64 FAIL: ffmpeg-libs-4.4-7.fc35.x86_64 How reproducible: Relatively quickly (in a minute) on multimedia pages full of codecs. Steps to Reproduce: Open some pages in my case from: https://www.idnes.cz/zpravy/archiv Actual results: Gah! your tab just crashed Expected results: No crash. Additional info: Firefox loads these libraries when ffmpeg-libs is installed. Unaware who initiates that load. There is no script to tell Firefox to load them. /usr/lib64/libavcodec.so.58.134.100 /usr/lib64/libavutil.so.56.70.100 /usr/lib64/libswresample.so.3.9.100
Do you see anything at about:crashes? Can you submit the reports and attach crash ID here? Thanks.

There's no such report at https://crash-stats.mozilla.org/ is it submitted? You need to do so explicitly at about:crashes page.
I do not know why. Now I have submitted 30a0745f-5ddb-1472-ef0e-4232c39be657 and it also does not appear there. After submitting it from about:crashes it disappeares from that page.
Okay, can you try mozilla binaries directly? (I expect under Wayland) https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries Thanks.
It was a bug in intel-media-driver from rpmfusion-nonfree, filed as: https://github.com/intel/media-driver/issues/1307 Sorry for the noise here, I was not aware how to debug the multi-process Firefox but in fact it works normally with systemd-coredump.
