"These changes are not driven by a desire by Mozilla to use people's data for AI or sell it to advertisers," Mozilla spokesperson Kenya Friend-Daniel told TechCrunch. "Our ability to use data is still limited by what we disclose in the Privacy Notice." The company clarified that its AI features operate locally on users' devices and don't send content data to Mozilla. Any data shared with advertisers is provided only on a "de-identified or aggregated basis," according to the spokesperson. Mozilla explained it used specific legal terms -- "nonexclusive," "royalty-free," and "worldwide" -- because Firefox is free, available globally, and allows users to maintain control of their own data.
