That's interesting. What is the change which broke it? Update from Firefox 93 to 94 or switch from Fedora 34 to 35? Can you do some investigation here? Also please try Mozilla binaries: https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries I see the HW acceleration is on so this should not be a problem here. Thanks.
The about:supports looks like VA-API is not enabled, so no issue with that. One important change from Fedora 34 to 35 for this setup is that the new crocus driver is now used, so this may be a Mesa issue. In that case, videos should work when running firefox with `MESA_LOADER_DRIVER_OVERRIDE=i965 firefox` or `MESA_LOADER_DRIVER_OVERRIDE=i915 firefox` (not quite sure which).
