I see that almost all 1-star ratings are about not being able to log in and the author has always given the same explanation and almost nobody reacted to that. Filtering all of this out, you will notice that this is a really good extension.

Love this addon but I've been unable to log in for quite a while now after changing my username. I didn't have issues logging in other times I've changed usernames so I'm not sure what the problem is.
