Rated 4 out of 5 stars

This is literally awesome, I use it all the time!

Although there I have some feedback:
- Bug - Switching Aero on or off in Windows 7 renders the awesomeBar useless. Can't see the url, can't click it or write anyting. Restarting firefox is needed.
- Bug - You have to make changes to the icons, for the settings to be saved in next session. IE, hiding categories without making any changes to the icons won't be saved.
- Feature - Would be nice to be able to rearrange the categories, both visually and when using TAB.
- Feature - Would be better if the hidden categories weren't present either when using TAB. Although this makes it impossible to unhide categories. (at least to my understanding)
- customization is key, but I think you already know that. It would be nice to be able to edit the icons, since there is no difference between the different google services. Creating your own categories would also be cool, maybe with a community-driven database.

This review is for a previous version of the add-on (12.1-signed.1-signed).
