Shows who unfollowed you on Tumblr.
I'm having the same issue as Banita, ever since the Tumblr update it has completely stopped working, and this was the only working unfollow checker since forever. I don't know if you guys still exist or do things but please look into this!
I beg someone to please fix this extension. sob. I wig out every time my follower count changes, thinking "oh shit, was it someone important?"
and checking out relieves me so much anxiety and stress to have answers/closure right away
