Firefox would normally copy the content of the previous bookmarkbackups folder to this folder in the current profile folder when you reset (refresh) Firefox and create a new profile. *Bookmarks > Show All Bookmarks > Import & Backup > Restore > Choose File If this didn't happen then you can browse to the bookmarkbackups folder in the "Old Firefox Data" folder on the desktop and restore a recent backup. *http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox The xxxx part in the bookmarks-####-##-##_xxxx_$$$$.json name is the total number of items in the file (includes folders and separators). ---- See also: *https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile *http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
