Forum Response - Restore default search engine

If you see a prompt like this:

This is a one-time prompt that allows you to choose default search engine when a third-party add-on has changed it without your awareness or permission. The prompt lets you confirm that you really wanted that change.

If you click No in the prompt, the change will not be made and your previous settings will remain.

To learn more about search settings, see Change your default search settings in Firefox.
