5500 people have tried Rock Your Firefox since it launched in August, and yesterday version 0.5 was released.

New things in 0.5:

• Invitation tool – easily invite your friends to add the application (if they haven’t already!)
• Preview viewer – clicking on an add-on’s preview image in the display page will now open a preview viewer to view all of the previews
• Friends that add the application will now appear in the add-on feed
• Misc. minor bug fixes – see the full list here

So, get started inviting all of your friends to Rock their Firefox!
