I opened firefox to see that the bookmarks had gone haywire. When I'd rollover one of my bookmark folders to the the contents of it, a little grey box would appear next to the folder where the pages were supposed to be. A few of the folders were working so I restarted FF. When I reopened it, all of the bookmarks were gone along with the folders. I tried restoring from a backup but it said it could not be processed. Also, the show all history does not work. It takes me to a blank page. I've tried rebookmarking but FF won't let me bookmark any of my older bookmarks.
