I have been trying to watch the video linked below with Closed Captions, but they won't appear. I tried opening it on other browsers, such as Opera GX, and it works just fine. I tried turning CC off and back on and reloading the page, it doesn't work. Please help.

That is weird. I see the closed captions if I start the video and immediately move the mouse out of the video. The captions disappear as soon if I hover the video and the controls appear. In Firefox 90 I need to close and restart Firefox to make this work again. In some Firefox versions it also works when I close and reopen the tab (Ctrl+W and Ctrl+Shift+T) and restart the video and quickly move the mouse away to make the captions reappear. In Firefox 68 this works better: I see the captions, but they disappear if I hover the video to make the controls appear but reappear if I wait long enough to auto-hide the controls or move the mouse out of the video.

Yeah, that happened here , too. I'm not sure if it's a problem with Firefox or with the website per se. Do you know any test I could make to be sure?
