Turn on address autocomplete in Firefox - Today's Browser Tip:

Here's yet another Firefox feature that's buried in about:config but which you won't be able to live without once you enable it: Address autocomplete. While by default Firefox will show you previously-visited sites that start with whatever you've entered in the address bar, when you enable this setting it will fill it right in where you're typing, so when the address you're looking for floats to the top you can just press enter.

In order to enable autocomplete in the address bar, first enter about:config in the address bar. Then right-click anywhere on the list and select New > Boolean and create a preference called browser.urlbar.autoFill. Finally, double-click on the item you've just created to set it to true. That's it!
