Anyone know how to change search engine in Opera v12? It keeps asking for a “string” when I try to switch to Bing or another one, and I have no idea of what that is...
Go to the search box in the upper right corner > click on the icon and you'll get a drop down menu > choose "Manage Search Engines" > Click on Bing and then Edit > in the pop up box click on the Details tab > check the box "Use as default seach engine" and/or "Use as Speed Dial search engine" Don't enter a search query.
Sometimes it will try to revert back to Google as your default search. To fix that: Go to "Manage Search Engines > click on Google > Delete > Problem solved!
