Be careful, your understanding of incognito mode in Firefox may be wrong and that could be costing you (discuss.tchncs.de)

All the incognito browser windows share the same "session" in Firefox. So say you open an Incognito window to browse Facebook or something, then you open another Incognito window, this new incognito window is linked to the previous incognito window, meaning you are logged into Facebook at that new Incognito window as well. This is because, as I explained before, all the incognito windows share the same "session"

The only way to clear incognito window is to close ALL of them and then create a new incognito window. You dont have to close the main non incognito Firefox window though, just close all the incognito windows. Then open a new one, now your previous session is destroyed and you are new again.

You may know it but its not that common knowledge as it should have been

I use it to test that I've set up an authentication system correctly without a cookie bias, among other uses

Set everything up in main > confirm tests pass > log in from incognito with password vault to make sure the auto test didn't lie.
