Yes, importing means that Firefox makes a copy of the IE favorites and convert them to the format that Firefox uses internally. Firefox stores the bookmarks and the browser history in places.sqlite and no longer uses an HTML file or creates an HTML backup for the bookmarks.<br /> There are 10 daily rotating JSON backups in the bookmarkbackups folder within the Firefox profile folder, one for each day that Firefox is started. See: * http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox ---- If you have problems with importing the IE Favorites in Firefox then export the favorites in IE to an HTML file and import that file in the Firefox Bookmarks Manager. If you do not have the menu bar in IE then right-click the toolbar at the top to enable the Menu Bar. *Export the favorites in IE to an HTML file (bookmarks.html):<br>File > Import and Export *Import the HTML file in Firefox:<br>Bookmarks > Show All Bookmarks > Import & Backup > Import Bookmarks from HTML See "Import from another browser" and "Import from file": *http://kb.mozillazine.org/Import_bookmarks
