This is related to the post mentioned here: https://support.mozilla.com/en-US/questions/811479 with a twist. In Firefox 4 if you shut down the browser without signing out of gmail you stay signed in, even after a full system shutdown and restart. I HAVE NO APP TABS etc, and my security settings are also normal (viz. no stay signed in etc etc) I also always use HTTPS (In earlier versions, if you didnt always use https, then shutting the browser wouldnt log you out. But if you always used https, you would be logged out) Heres what happens: First let me make it clear that I have no app tabs, and all the other settings are correct (viz. no stay signed in etc etc). Now say one of the open tabs is my mail inbox. If I close and restart browser, I'll be in my inbox!! (Earlier versions of firefox took me to the login page). Whats the issue here? Does everyone else also experience this?
