Update: Problem solved, see https://social.tchncs.de/@jesterchen/116507474211504775
What do I do about "no video with supported format and mime type found" in firefox on linux? Many videos aren"t playing, while youtube works without problems.
If I open the not working vids in chromium, there are no problems either. If I download and mplay/vlc them, no problem. If I download them and open them locally: problem.
I"ve a fresh installation (including no prior profile dir), have installed betterfox, ublock - nothing different than my other systems. I simply cannot see some vidz. :(

@[email protected] Turns out: I was running Firefox ESR 140.9.1 (Kali 1.0). After switching to the default release, videos are no longer a problem. Thanks again.
