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."


  • Information in this article applies to Opera 12.16. Procedures may vary with other versions or products.


  • After disabling auto complete Opera still displays search suggestions in the address field, but does not use your history for this feature. Clear the "Enable search suggestions in the address field" check box from the "Search" tab of the Preferences window to disable this feature as well.
