Firefox includes several search options, but Google pays Mozilla to be the default option in many parts of the world. If you do not want Google to see your searches, you can change to another search service such as Bing or DuckDuckGo. More info: [[Change your default search settings in Firefox]]. If you prefer a different site, you may need to add it on. There are various methods for that depending on the site, so if there's one you want to add, we might be able to help.
