2 serious bugs Rated 2 out of 5 stars
1) some characters are replaced with something else once you export the passwords. for example & is replaced with %26
2) after changing my Gmail password through WebMail Notifier, all the passwords got wiped out!!! (thank god I made an export before that happened)
It is a very dangerous and useful extension.
this should be built-in to Firefox and make it less buggy.
