> You give Mozilla the rights necessary to operate Firefox. This includes processing your data as we describe in the Firefox Privacy Notice. It also includes a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content you input in Firefox. This does not give Mozilla any ownership in that content.
This new license to the data that you enter into the browser is only for local operation of the browser itself, not for ads or sponsored suggestions. In addition to that license, they also use the words that you type into the urlbar or search box to customize the ads and search suggestions that you see. It is important to keep these two things separate, because only one of them is new. The other has been there for years.
