Works great! I have one suggestion. It would be better if it did not hide your other tabs when you switch to private browsing. It would be better if you could have regular and private browsing tabs open at once. I didn't want to get this add-on at first because it is version 0.1.This review is for a previous version of the add-on (0.1.1-signed.1-signed).
"It would be better if it did not hide your other tabs when you switch to private browsing."
I agree, but that's nothing that I can control: Firefox's private browsing mode works that way currently and my add-on only uses it, it does not replace the way Firefox works. Sorry! :-/
