That's not the reason for this problem though.

As I wrote in another mail:
Firefox doesn't support libavcodec58_91 yet, an update to fix that is already 
on the way to Tumbleweed:
http://bugzilla.opensuse.org/show_bug.cgi?id=1174286
https://lists.opensuse.org/opensuse-factory/2020-07/msg00328.html

This is not a Packman-specific problem though, libavcodec58 has been 
dropped/updated in Tumbleweed in general.

Another workaround for now would be to install libavcodec57 from Packman, 
Firefox would use this if it finds it.

Kind Regards,
Wolfgang
