After reading recently, here I think, that any addon can be a security risk, it feels a bit risky installing ones for just one site.

I use Redirector [0] to perform this and other sites redirections for me (Twitter --> Nitter instance; Instagram --> Bibliogram instance, Zoom calls --> zoom web calls). So, at least it's not for just one site.
