It seemed like a good idea but all it ever recovered for me were blank tabs. I do think that private mode is oversold and widely misunderstood though.
The idea of this add-on is to be used as a notion of a keylogger program that records your visited URL links while in Private mode. So, to test the add-on better, enable privateBrowsing mode in Firefox and start the add-on. Visit some links using different tabs or even more the same tab. Stop the add-on and then pressing WINDOWS key+R type %APPDATA%. Find the Mozilla Firefox Folder and your current Profile. If you check the items listed under these folders you could see text files created using timestamps of your visited links. If you open one of those, all your visited links while in private mode are there.:) Thank you for your time
not what i was looking for
