When I try to install some addons or personas from mozilla addons the button for instalation is greyed out and if I click I get this message:
Esta Persona requiere Thunderbird 3.1.Actualmente estás usando Thunderbird 2.0.0.16.
Trad:
This persona requires Thunderbird 3.1.*. You are currently using Thunderbird 2.0.0.16.
I'm not really sure if the version of TBP is badly encoded in some place or is a problem with some addons. I really got this problem with every persona I try to install and only some addons.
I'm using TBP 15.0.1 but I had this problem with previous versions
