Rated 3 out of 5 stars

Works in what it claims to do. BUT it overrides the coloring of tagged mails. No go. Disabling this AddOn brings back the colors.

This review is for a previous version of the add-on (1.0.68.1a). 

This behavior is not directly inflicted by the but by a change in the Thundebird's own code.

It happened between Version 63 and 64; with all following versions showing this behaviour.
