This should do it::





1. Click the Tools-%26gt;Options menu item.


2. Click the Privacy tab.


3. Under History, deselect the Remember visited pages check box.


4. Click OK.


5. Log out of all Firefox browsers.





When you log back in, the list should be clear and won't gather more entries.
