Thunderbird 3 hope Rated 5 out of 5 stars
Actually, I'm very sad for not being Crossover compatible to TB 3.03.
This is the ONLY clearly readable theme I've ever found, either because of the fonts it uses or for the colours of accounts which have unread messages.
I tried to change the install.rdf file and it works but there's a problem in the header of messages.
Please, fix it for TB 3.x!
