CloseReview for Gmail Manager-community by tester2011
Rated 4 out of 5 stars
Yep, same issue - displays the GMail webpage and have to manually enter the password.
Another recent annoyance (bug?) is that the mail snippets windows often appears at the mouse-location, rather than popping up at the appropriate location on the add-on bar.
