I open Firefox 16.0.2, Windows XP, and find my bookmarks system corrupted. Site names have the wrong addresses attached. i.e there is a random mismatching of bookmarked, names and address. also.. i find i can not delete folders, or content within folders, or rename/edit, site names. I find previous deleted bookmarked sites, restored.

I have read the help page on deleting the sqilte file. I have to import and restore my bookmarks every time i open Firefox. what to do?
