Hi folks I have to admit to being in a bit of a panic. Something flashed onto my Firefox browser screen and then I lost all my saved top line tabs, my home button and all the tabs that auto-load each time have also gone. I have never had this happen before and I cannot understand how to roll back. I have noticed a new folder on my W10 Desktop PC's Desktop called "Old Firefox Data" and I am hoping someone can tell me whether that might be helpful when you help me restore things. Any thoughts?
