Only on Firefox (not Chrome, for example) animated gifs and videos on Twitter will not display -- they instead show a black screen. When paused or not yet played, there is a visible image, but as soon as I press play, it goes to black. The audio on a video will play just fine, but the screen/image is still black.

I have checked my graphics drivers for updates and they are all up-to-date. Also the gifs/videos play just fine if I use Chrome.

Firefox is up to date. I'm on v 93.0 (64-bit).

Note that the animated GIFs also are short MP4 videos. You can check the Web Console for media related messages.
