I use the closed captions (CC) in YouTube videos with FireFox. Lately I have been seeing videos that seem to misbehave. At the very start of the video, ALL the captions display at once, one after the other. Then, as play continues there are no more captions. Most videos still show captions normally, that is, captions appearing only when the dialog matches them. But a few videos misbehave by showing all the captions at once. Here is one such video.
I noticed this misbehavior within the last month and assumed that the video was doing something peculiar with the timing of the captions. But when I use the YouTube Show Transcript option to display the captions and associated timing outside the video, the transcript looks quite reasonable.
One further oddity, if I take that same URL and load the video in a different browser, for example, Chrome, the captions are displayed normally.
I've included a screen shot of the video in YouTube showing all the captions displaying at once.
