The Opera Web browser features smart browsing technology that uses your previous searches to auto complete the URL you are typing in the address bar. You can disable the auto complete smart browsing feature if you prefer not to let other users see which sites you have visited in the past. Opera allows you to specify how many addresses it remembers for auto completion purposes so changing this setting to "0" disables this smart browsing feature.

Step 1

Open the Opera browser and click "Tools" from the Menu bar.

Step 2

Select "Preferences" and then click the "Advanced" tab.

Step 3

Click "History" and then click the "Clear" button next to "Addresses.

Step 4

Select "0" from the Addresses drop-down list and then click "OK."
