1) Open the bookmark manager (Ctrl-Shift-O) and select "Import and Backup => Export HTML", then save to "~/.mozilla/firefox/*.default/bookmarks.html
2) Type about:config in the address bar, then use the filter bar to search for "browser.bookmarks.autoExportHTML" and set this to "true" by double clicking or selecting and pressing enter
