Video playback bug on Firefox with WebGL build using Unity 2022.3.37f1

Hi everyone,

When trying to play the video with Firefox, the video seems to try to play but every second the video starts again or at least, it looks like it. It works fine on Chrome, Safari, Edge…

I created a simple project to debug it

I have already tested quite a few things, but the issue is always there.
Does someone have an idea or is it really a Unity Bug?

You can check out the bug here with the latest version of Firefox:
Unity WebGL Player | InternalTest (owliongame.be)

Well, a temporary fix has been found just by installing this player in the project… WebGL Video Player | Integration | Unity Asset Store

Still looking for a clean fix
