Loved this add-on originally, but it has not worked for a couple of months now on my android (S25+). It works flawlessly on my linux laptop though.

Is this add-on open-source?

Needs access ONLY to youtube and ..dislikeAPI websites. Thats what we need in comparison to more popular returnYTdislikes which now asks for access ALL websites content, browser and websites activity, without targeting specifically youtube website.
