Importing bookmarks into browsers helps keep your browsing experience organized and complete. The process is quite similar in most browsers, although Internet Explorer uses a somewhat different lingo.
Later versions of Internet Explorer have gotten better in terms of speed and safety. Developers will often recommend other browsers like Chrome or Firefox, as they are more advanced, run faster and have an overall less bloated feeling. A favorite of mine has always been Opera or Chrome. They are superior browsers with lighting speed.
