How can I get the search bar at the top to not auto fill my bookmarked sites when trying to enter a search? If, for example, I enter "f" it automatically fills in facebook.com and will continue from the end of ".com" with what I am typing to search. This happens every fourth or fifth search that I do Both browser.urlbar.autocomplete.enabled and browser.urlbar.autoFill are both set to 'false' and the device has been rebooted several times...
