Can you make the a replica of the Stealther? It seems the author of Stealther has disappeared and he isn't updating it to work with FF4. So, like instead of blacklisting anything, just pressing a button on the bar to disable history, cookies, closed tab list, etc. That would be super.This review is for a previous version of the add-on (22.214.171.124.1-signed.1-signed).
An undertaking like taking it upon myself to update Stealther (a huge addon, btw) is probably more than I am willing to do at present. Have you tried the FF incognito mode? Private Browsing, I believe is what it's called. My gripe with that is that it opens an entirely new window rather than a single tab.
