Below are three options on how to change FireFox’s new Awesome Bar settings.  Personally I love the new URL bar and actually use bookmarks and tags now and thanks to Foxmarks all my computers have the same bookmarks.  However in the case of my girlfriend she didn’t like the new feature so below are your options if you fall in the same boat:

Option A: Disable autocomplete drop-down entirely

Use this if you don’t want Firefox to display any kind of suggestions in the Address Bar be they from your browsing history or from saved bookmarks.

Open the about:config page and set the value of browser.urlbar.maxRichResults as –1. Restart Firefox and your Firefox 3 address bar will behave just like that of Firefox 2.

Option B: See web addresses that you have typed

In this option, the drop-drop remains enabled but it will only suggest website addresses / URLs that you have previously typed in the location bar.

Open about:config and set the value of browser.urlbar.matchonlytyped to False. Now none of the entries from your browser history or bookmarks will appear in the ‘awesome’ address bar.

Option C: Remove Bookmarks Completely from Address Bar

This is probably the option you are looking for. Firefox 3 uses the Frecency score to determine sites that should appear in the drop-down. We can set frecency value for bookmarks to zero and thus they won’t appear in the location bar.

Open the about:config page, and set value of places.frecency.unvisitedBookmarkBonus and places.frecency.bookmarkVisitBonus to zero.

Setting places.frecency.unvisitedBookmarkBonus to 0 will prevent bookmarks from appearing that you have never visited while places.frecency.bookmarkVisitBonus will prevent display of bookmarks that you have visited since the last time you cleared private data in Firefox.
