This is a plugin I found recently and really enjoy. It gives you the opportunity to redirect several webpages to alternatives. For example Youtube to FreeTube or Piped. If I search for youtube in Firefox, FreeTube automatically opens and shows me my feed. I like it, I use it, I can recommend it.
Maybe the devs don’t know that. Could you open an issue on this?
Asking you because you may know more about these permissions than me.
I’ve been using the addon for some time, and while it’s good now, there were some silly mistakes in the past. What I’m trying to say is that maybe they’re just relatively a beginner, and it haven’t yet occurred to them to revisit the permissions.
