Hi, You can export the bookmarks to an HTML file via '''Bookmarks''' ('''Alt''' + '''B''') > '''Show All Bookmarks''' > '''Import and Backup''' > '''Export Bookmarks to HTML''' which can be later used to '''Import Bookmarks from HTML'''. You can also take a backup of the '''bookmarkbackups''' folder in the [http://kb.mozillazine.org/Profile_folder Firefox Profile Folder] or the latest dated .json file inside. This folder or file can be copied or put back to '''Restore''' from the previous menu Yet another way would be to backup the '''places.sqlite''' file which holds the history in addition to the bookmarks.
