Review for Account Colors by tommybelgium
Rated 5 out of 5 stars
I agree with all the other latest reviews, it is indeed very frustrating that after each update of Thunderbird several great add-ons like this one can't be used anymore. So yes I am also very much looking forward to the updates of Account Colors so they can be re-installed and activated again!
