Firefox 3 has some nice features at the same time it came with one useless feature called Awesome Bar. Ok some may like this one, but i don’t like it, the annoying part is that it shows all the bookmarks stored in firefox when entering URLs.
Now it is not annoying anymore, there is a Firefox Extension that takes care of this feature. The add-on is Hide Unvisited, which hides bookmarks from appearing in the Awesome bar. If you visit those bookmarks before deleting history they will appear but if you haven’t visited those sites they will never appear in awesome bar.
