Why let website owners control your identity? Why force other users to talk to you in the clear? This plugin solves that problem.

Small bugs: It sometimes prevents the spellcheck from changing things. And it doesn't tell you when it's doing something slow and important, such as generating keys.
The Webpg drop down menu on form boxes would benefit from also appearing on the submit buttons.
Precomputing some default pgp keys and using mozilla-sync to share amongst other devices would be a great help!

Keep up the good work!
