works for me TB3.0 Rated 5 out of 5 stars

even the gravatar thing works (i made an account for my own email address and uploaded a photo), takes a few seconds, but once it's downloaded, seems to be instant. nice!

and i can open the contact card for the sender if they're in my address book, too. cool add-on. my new favourite :)

This review is for a previous version of the add-on (0.1.6).
