I needed to upgrade to the latest version, where my previous version was being discontinued. When I clicked the button to, download and upgrade, Firefox closed, and nothing else happened, it didn't relaunch. What actually happened was that version of the Firefox .exe was removed, not updated, and I lost all of my current work and open tabs. Well I reinstalled and got my bookmarks back, but not the closed tabs. How can I get those back? I had 20+ open and need to review what I was working on previously. Thanks, Steve
