Firefox 3: Clearing address bar history

Unfortunately, just going to Tooss -> Clear Private Data and selecting Browsing History does not get rid of the address bar URL history. To at least stop the history of previously visited web sites coming up whenever you enter an URL in the address bar, you can set the parameter that controls the number of lines displayed in the drop – down list to 0 (zero):

Go to the list of configuration parameters by typing about:config in the address bar:


Find parameter browser.urlbar.maxRichResults. By default, this value is set to 12.


Double-click the parameter to change its value. Set the new value to 0.


Click Ok to confirm, and you're done.



Note that the change will only be effective after closing down Firefox and starting it up again.
