Exhibit B: https://www.mozilla.org/en-US/about/legal/terms/firefox/

When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox.

I don't agree to this as written; and I am not inclined to give them the benefit of the doubt given Exhibit A. I think an argument could be made that selling my data to advertisers would help me "experience" and "interact" with online content. Perhaps it would be a difficult argument, perhaps not. I think skepticism is warranted.

Firefox has struggled to find a profitable business model outside of Google paying to be the default search engine, and it looks like these changes are a pivot to address this. I don't think it will be good for users.
