Once it was my favorite password manager for firefox but.. Rated 3 out of 5 stars

I am a long time firefox+laspass user. But after recent fx update, lastpass hangs firefox when I am offline and lastpass tries to contact login server

This review is for a previous version of the add-on (2.0.20.1-signed). 

Reinstalling from LastPass will fix

Hello,
