Mastodon – Simplified Federation
This has always been one of the annoying things about remote interactions in Mastodon: While you can seamlessly follow remote users and reply, boost, etc. through your home instance, if you just visit a remote user or post in a regular browser window, you have to jump through a few hoops to pull it into your own account’s view.
This automates the hoops.
Setup is simple: You enter your home username and site in the preferences.
Incidentally: Remember your username is case-sensitive! If you have mixed case in it, you have to type the capitals correctly!
