Not sure if I am missing something, but this is something I can do without any extra extensions installed? Out of the 27 accounts I am currently following, 20 are accounts from other Mastodon instances...
I do have to search for the account on my local instance to start following them instead of being able to click follow right there, but that is a minor annoyance
