Report "Mozilla Firefox 3.66, Win 7 Home Premium: No matter what I try, Firefox will not save my open tabs. Whenever I reboot or FF crashes, I have to recreate all the tabs I have open. I have tried changing my homepage (Yahoo Mail), and "Show My Windows and Tabs From Last Time" is always selected. Nothing works, and I spend hours of extra time dealing with this problem. The only time the tabs are saved is when there is an Add-on update and I have to re-start Firefox; then it starts exactly right"
