The extension is currently in beta stage. Anyway, the most important features are implemented and the extension is fully usable! We encourage you to contact the FireGPG Team if you find a bug.

Additional Notes:
FireGPG isn't a key manager. You must install the GnuPG software!
On GNU/Linux and Mac OS, it's GnuPG. You can install it with your favourite package manager (like Synaptic, YaST, Yum, etc.) or from its official website.
If you are using Microsoft Windows, you have to download WinPT and GPG, and install it at the default location.
If you already installed GnuPG on your system, but in an uncommon place, you may still manually set its location using the options dialog of the extension!
Source Code:
You can download the source code with Subversion:
