Today I realized coincidentally that cookies between incognitowindows are shared, didnt think about this before, I just assumed that a newly opened incognitowindow from the main window was a new fresh one. It turns out not to be.

A quick googlesearch shows that its not just be, theres several others who came across this a long time ago. Theres even a bug filed for it, although the status wontfix is not very optimistic, see issue 24690.

Some of the comments on the issue refers to the multiple profile work thats beeing done instead, it looks like a good idea, but seems to need some preparations before use. I’ll definitly try this in the near future..

See the user dropdown in the right corner of the window.
