I've set the option to "Show my windows and tabs from last time" enabled. I use it every session, and normally it works great. - EXCEPT; If I click a link in an email (in Thunderbird) when FireFox isn't already running, it loads a set of tabs from a session last November! I've checked in history, and it doesn't list the tabs opened when I closed the browser, just the tabs I closed in previous sessions. Is there any way to fix this? And, is there any way to find a list of the tabs I had opened before I ran update and had to re-boot?
