Your bookmarks might still be inside firefox folders though...    look here:    Documents & Settings/[Your User]/Application Data/Mozilla/Firefox    there're folders in here named profiles inside them there are some folders named with a random number and inside there're bookmarks, bookmark backups, among other things....    try running a search on this folder:    Documents & Settings/[Your User]/Application Data/Mozilla/    for htm or html files....    what might be happening is that for some reason your profile folder is being recreated or something like that... but the old profile (with your data) might still be in there...    good luck! :clink
