Recently, I opened up the Firefox browser and it prompted me to create a new profile. I reopened the browser 2-3 more times and the same thing happened. I created a new profile. My bookmarks immediately disappeared. When I went to look for my old profiles, they all had disappeared, also. Firefox has been updated recently, and so has Windows 10. I have an older (2013) Toshiba laptop. Any suggestions for getting profiles and/or bookmarks back?
