Rated 5 out of 5 stars

I've just installed this add-on. It's absolutely useful when you do not feel like open the browser for some link you're not sure about, or simply seems totally uninteresting. And after all, it's very comfortable to use it, works perfect, no side-effect for Thunderbird, looks clean, user-friendly designed, embeds the browser very fast instead of the message field. It's surprising and a very good idea.
Congratulations and I will look for more. That's what I call a real add-on.

This review is for a previous version of the add-on (3.0.1).
