>>>Doesn't stay active for me.
Well, this is weird. Anyway, I've managed to fix this issue by myself. The problem for me was in browser.css in this line: "border-left: 1px solid rgba(10%,10%,10%,.4);", I've simply changed "1px" to "0px".

Looks awesome, but there is still one little issue that presents me from using this theme instead of the same author's Firefox 3 theme for Firefox 4+. In Firefox 3 theme if I put my cursor over the back button and then drag it to the left border of the screen, the back button stays active and can be pressed from this position. In Firefox 3 Aero theme for Firefox 4+ it can't. If that can be fixed, I'll totally go for Aero.This review is for a previous version of the add-on (1.0.0).
