Absolutely goated add-on. I thought it was nigh impossible, or at least extremely tedious, to do this (and perhaps it was lol).
YouTube's massive redesign in 2017 was severely disappointing and I've been dying to find a functioning add-on for Mozilla that reverts YT back to any of its former UIs.
More than three large thumbnails fit on the homepage at a time, lack of shorts, generally more functional, etc!
