Rated 4 out of 5 stars

As I wrote in the subject, I found thi addon useful for my job, unfortunately when I installed it using TB52I got a black area where the button area of addressbook tab/window is and so I could not make any choiche. Probably the style colorcss must be reconsidered. If the author wants I can send him a screeshot of what happens.

This review is for a previous version of the add-on (1.0). 

Hi Topoldo,
i am currently working on this "bug".
The problem is, that thunderbird uses its own css for certain elements and i am not able to change this in a way that all themes are supported.
I have now an idea how to solve this issue and I hope to fix it this or next week.

*** new Version available color is fixed ***
