Rated 5 out of 5 stars

A must have add-on for the busy office!
My daily work involves sending emails from numerous identities, and forgetting to select the appropriate email was big pain in the b.tt until I found this add-on. With the color coded accounts mistaken identities are thing from the past.
Mozilla should include this add-on in the standard package.
The developer is responsive and open to the users. I contacted him with a small bug, and it was fixed in days.
I strongly recommend this add-on!

This review is for a previous version of the add-on (1.5.3).
