Re: [Trisquel-users] IceDove / e-mail client

I had the same issue and resolved it by downloading the latest version of  
Thunderbird.

I'm new to GNU/Linux as well and could easily be wrong, but it's my  
understanding that the the Mozilla branding issue has been resolved and that  
IceDove will no longer be maintained.
