This happens with any kbin/lemmy community/user. Mastodon seems to automatically redirect, I'm asking if I can turn that off somehow. If I go to a mastodon.social url, I expect to arrive at mastodon.social not kbin.social or lemmy.world.
As I understand it, that addon you're referring to would just redirect a lemmy.world link to kbin.social (aka my home instance) instead. Which isn't really what I'm looking for at all.
