hi, known firefox bug with standard html {overflow-x: hidden !important; }
( https://github.com/code-charity/youtube/issues/1649 )
and we can just avoid it in all future version. Just didn't make it to top1 of my to-do list :/ Whew.

hi! what are the hobbyist parts? The github preview? Prefer a full page UI? (our current one allows to check the change on the Youtube site the same moment.)

Bad/unfair. You should rate us for the many things we do already. (Who said we would predict every YouTube change immediately 24/7/365 and if you want it or don't want it? ~2x impossible) - Yet you can have a look in our list of topics in the bottom of the extension: https://github.com/code-charity/youtube/issues/2178 (Where you can see how. While you dont need us for this, we might also provide it soon to save you from copy&paste)
