Rated 5 out of 5 stars

A very straightforward add-on that allows users of all levels (and those without prior encryption experience) to use high grade encryption.

Instantly encrypt/decrypt web based email (using a web browser to read email - for example Gmail, Hotmail).

What I find useful about WebPG is that:

- Installs as any other Firefox add-on; easy!
- Colourful, easy to view settings menus (see screenshots).
- A novice can be locking down and securing their communications in less than 5 minutes.

Simply the easiest PGP based encryption add-on or application I've seen to date.

Welcome to the age of privacy & security through industrial grade encryption.
