Hi Dawid, if you run an unbundled version of Windows (in countries where the antitrust settlement prevents Microsoft from preinstalling media components), you need to add them on. See: Fix video and audio problems on Firefox for Windows N editions.

If your Windows already has those components, could you check the following test page. It's my copy of the old YouTube HTML5 support page. You should see all "supported" or "probably" entries. Are any of them not supported?

Open Jira. Open any uploaded mp4 file.

On some versions of FF it works, on some it does not.

I have encountered this error only on substack and only recently (last couple of months or so). I have Windows 10 Pro, Firefox 108.0.1 (64-bit) and I just cleared my cache and cookies, again -- disabled privacy badger and Ublock and I still can't run videos on substack.
