FireFox 3 Tip: Turn off address bar history

Here is how to turn off this annoying feature:

1. Type “about:config” (without the quotation marks) into the location bar
2. Click the “I’ll be careful, I promise!” button
3. Filter “browser.urlbar.maxRichResults”
4. Double click the row and reset the value to “0″
5. Close Firefox and re-open it.  Until you do, 1 URL will keep showing.
