Crash when clicking on picture-in-picture mode

Not a big deal, but clicking on Picture-in-Picture mode when the extension is enabled and a video is playing crashes Firefox. Maybe disable the PIP button when the extension is enabled (if this is possible) ?

I can't reproduce this on Win10. The fact that it crashes all of Firefox is odd - perhaps a clean install of Firefox would help, as recommended on Firefox's own crash information page. There's a lot of other great relevant information on that page as well.

Hiding the element is certainly possible, however. If you mean the miniplayer button, its CSS class is "ytp-miniplayer-button". A bit of simple CSS à-la:
.ytp-miniplayer-button { display: none !important; }
eliminates it nicely enough on the Desktop version, if you need to hide it for yourself (:

I am not an admin on my system, but I will try to reproduce this at home, with a clean install. For the record, I was using Firefox 98.0.2 (64-bit) on Ubuntu 20.04.3.

It doesn't bother me at all, just thought it could be a minor issue for some people.
