Rated 3 out of 5 stars

Breaks certain AJAX site logins. Clears username field even when no username or email is given in options.
If the extension would not touch any other field but the password when not requested to do so, pehaps both bugs would be fixed. Until then, I'm afraid I cannot use it, which is too bad as otherwise it was very nice to have.

This review is for a previous version of the add-on (0.6.1).
