Plugin for using pgp encryption with gmail

Question

Are there any Firefox or Chrome plugins for encrypting/decrypting and signing/verifying emails for web based gmail? I have Thunderbird setup to do this but I'm interested in doing this on a browser.

Firefox had a plugin called FireGPG which does exactly this but the developer abandoned the project and now I can't find anything that's similar.

Answer 1

The browser is really exactly the wrong place to be doing this. It is possible (as FireGPG proved) but very hard and annoying to keep up with the constant changing in Gmails crappy interface (as FireGPG proved).

Use a real MUA and you should be fine :)
