I'm running Firefox 83.0 (64-bit) on Ubuntu Linux 20.10. Whenever I open a YouTube video, there is a banner blocking the top 1/4 of the video saying: &pictureInPicture.label;


^ (the caret is under the ampersand)

It doesn't matter if the video is on the youtube.com site, or on a Zoom.com site.

Did you try in Safe Mode?

This usually means that a label translation in your Firefox installation is missing or broken. This might also be about a feature added by an extension.

What Firefox locale (user interface language) do you use ?

Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.

When I restart in Safe Mode. I don't get the problem. In normal mode, if I try disabling each add-on one at a time, I get the problem. I re-enabled each add-on that was disabled before trying disabling the next one, so I can keep track of them. I'm running 83.0 (64-bit) for Ubuntu canonical.

I tried, in normal mode, to disable each of my extensions, then re-load a youtube page. The error banner appears, even after I disable all my extensions, one-by-one.

I even tried restarting after no add-ons were enabled, and the error banner still appears. Oh, and I'm using the English (US) locale, default theme.

Can you answer the question about what Firefox locale you use ?

This is about showing the controls if you hover the media player.

English (US).

I tried the Mozilla release 83.0, and the banner did not appear. (yay!) Neither did my passwords or my 1002 tabs. (boo!) I installed all the same add-ons and the banner did not appear. (yay!)

I closed the Mozilla version and re-opened the Ubuntu version 83.0, with all the same add-ons installed, the banner does not appear! (yay!) But, I have no clue as to why. (boo!) But tabs and passwords are still there! (yay!)
