I wouldn't call them "obvious" reasons but I recently discovered that in Google Sheets under FF I couldn't duplicate a tab or copy a tab to a new sheet. I had to fire up Chrome to do that.

Oddly enough, Chrome had somehow lost my settings since the previous time I started it a few months earlier, as if it were a new install. :-?

I've not noticed any problems under YT Premium so far.
