Rated 5 out of 5 stars

I'm constantly switching between windows all day long and to have TB in the mix is annoying because I keep clicking on it accidentally. Minimizing it to tray is a requirement and while it was unavailable since the latest upgrade, I was going nuts! So Thank You Very Much!

This review is for a previous version of the add-on (1.4.3). 

I totally agree, email software should be minimized, that's why I try to revive this extension ;)
