Discontinued. Used to fully restore the 2021 YouTube watch page layout, now only partially restores it. The method it uses could stop working any day now.
I made CustomTube, a much better extension that does what this extension did and much more. Users of YouTube Watch Page FIx will most likely want to select the 2019 layout in CustomTube. Install here: https://addons.mozilla.org/en-CA/firefox/addon/customtube/
