When I try to play whatever video on X in Firefox Nightly mobile, it just shows sequences of solid colors. Audio is still normal.

The issue happens for both GIFs and Videos This only happens in Firefox Nightly. In Firefox, the videos can be seen just fine.

I had this problem on Bluesky and Discord embeds (whether hosted on those services or embeds of YouTube) for a few days until this morning (2025-11-23), it seems to be fixed as of the latest update (20251123083951). Came here looking for a report about it, I'll keep looking around to see if it's in bugzilla somewhere. Running on a Google Pixel 7a here, if relevant.
