Over the last week, I've noticed that my Bookmarks in Firefox keep disappearing, it's happened before but they've always come back when I've closed my browser and restarted. Today I went to the Bookmarks and they've gone, I tried closing the browser and restarting my desktop computer too. I've look at every help I can but I can't get the Bookmarks back. I've got (I had) a lot of Bookmarks and preferred to go through the Bookmarks to get to the sites I want. I like Firefox but I really do need the Bookmarks to show. Also, when I tried to import my backup(s) it wouldn't do it either. I've run Norton full scan but it found no threats. I'm on W10 Home, 64 bit - Microsoft hasn't update in the last week so I've ruled them out too. Would some kind person please help, I'd be most grateful as I've run out of things to try - by the way I'm not a techie. Many thanks Christa
