We LOVE Firefox but have had a few problems with the Sync feature. Sold an older laptop and want to 'unsync' it from our collective account without affecting said account. When I 'disconnect' or 'unsync' it, I do not want to affect any of my collective bookmarks, sync settings, etc. I accidentally discovered that what I do on one system affects all 4 of our systems without allowing for some system differences. When I was trying to delete unrelated bookmarks on our children's computer, those folders and files were deleted from all our machines, which I did not want to do. I found no way to recover once the files were gone. We are proponents of natural health for example which holds no interest to the children, and when I deleted the 'Health' file, 2 years of research sources were lost!!! I am not a computer nerd nor even close to being an accomplished user so we need some help. thank you in advance for your assistance. Bren
