Rated 4 out of 5 stars

This has been a must-have add-on for firefox. However, I'm not too excited about the sudden font change in version 0.7.

I would've given it 10 stars if the fonts hadn't changed.

This review is for a previous version of the add-on (0.7.1-signed). 

The font change is done my Google themselves. We released an update to the styles this afternoon to fix some changes they've made.
