Rated 4 out of 5 stars

After update to ver. 6.6 I cannot see any options on Account/Identity Colors tab in addon-options window - only blank tab under it`s name.
In version 6.5 everything was OK.
Thunderbird 17.0.3. (!)

This review is for a previous version of the add-on (6.6). 

This problem is fixed in Account Colors 6.7.
