Since the latest stable firefox version (95.0.2), it seems like opening a video file which can be played in the browser, like a mp4 file for instance, will result in an error:
05:05:35,632 Uncaught TypeError: videoElement is undefined
The video will plays normally, just to make it clear. Just that the error will appear in the console. And the error will keep reoccuring.
Here are some video samples if you need, to see if the error is individual or global.
