Mozilla’s updated Firefox’s address bar with an add-on that improves history searching, as well as adds a bunch of custom search engines to help you search by subject—like books, maps, movies or music.
Firefox’s AwesomeBar has always gone above and beyond the call of duty, but Awesomebar HD adds a few cool new features for search-hungry Firefox users. The first thing they’ve done is improved history searching: now, Firefox pays attention to how often you visit and re-visit certain pages, so when you type in the name of a previously visited page, it can intelligently order the results in a way that gets you there quickest.
