Rated 4 out of 5 stars
This is a great addon for people with multiple email accounts. I'm using Thunderbird 8 right now and it isn't compatible.
Will there be a version that supports Thunderbird 8?
Compatibility updated for Thunderbird 8.0
Account Colors 4.2 compatibility was updated to Thunderbird 8.* on 7 October 2011. If you downloaded Account Colors 4.2 before that date, then you should remove it from your Thunderbird and download it again and re-install.
However, if you have found something in Account Colors that does not work correctly with Thunderbird 8, then please e-mail the details to: email@example.com.
