Hello,

There has been an upgrade of Firefox ESR to version 128.3 on Debian 12 bookworm.

Before the update, I could play videos, now I can't.

I precise I can play videos on Chromium, or with the video players.

I have libavcodec58, libavcodec-extra59, ffmpeg 5.1.6 packages installed.

There is an error in the console: Media resource xxx.webm could not be decoded. Specified “type” attribute of “video/mp4” is not supported. Load of media resource xxx.mp4 failed.

This command seems to indicate the session is X11 and not Wayland: ``` loginctl show-session 1 -p Type Type=x11 ```

I have ended up installing latest Firefox from Mozilla repo.

It can play videos :)

That's the same OS I'm on and was watching a YouTube video before coming here.

I use Firefox straight from Mozilla as I've always found it to work better than when installed from the official Debian repositories.

I'm currently on 131.0 but had no problems with 128 when I was on that. Again that was 128 from Mozilla rather than 128ESR from Debian.

Note: I have tried switching from X11 to Wayland and the issue persists.
