Rated 5 out of 5 stars

Best addon ever, together with Firebug.
I am a web devolper, I often need to create fake accounts on my sites to test various logins and other stuff. This addon is incredibly useful.
And when I browse the web in free time, I never give my real email address, always using Trashmail.

This review is for a previous version of the add-on (2.5.11.1-signed).
