Mozilla Thunderbird is a redesign of the Mozilla mail component. The goal is to produce a cross platform stand alone mail application using the XUL user interface language.

Reviewing 52.0 Beta 4 (Mar 14, 2017)
v52.0 is the shot in the arm this app needed. So much faster than 45.x series.

You can't fix stupid.

I only hope the addons i use will be updated to work with
