Mozilla has updated its Firefox Terms of Use for the second time in a week following backlash over language suggesting broad data rights. The revised terms clarify that Mozilla only requires rights necessary to operate Firefox, without claiming ownership of user content.

Changes in Data Licensing Language

The initial terms, effective February 26, implied a broad license over user data. The updated version specifies a nonexclusive, royalty-free license solely for operating Firefox as intended by users. This update aims to address user concerns about data privacy and ownership.

Transparency and Privacy Practices

Mozilla introduced these terms alongside a new Privacy Notice to enhance transparency. The company stresses it does not sell user data, responding to varying definitions of "sell" across jurisdictions. Mozilla collects some data through optional ads and sponsored suggestions to maintain commercial viability.

Data Collection and Privacy Measures

While Mozilla doesn't access conversations with third-party AI chatbots, it gathers usage data to improve Firefox. This includes chatbot selection frequency and prompt usage. Mozilla ensures shared data is anonymized or aggregated, employing privacy-preserving technologies like OHTTP.

Context of Broader Privacy Concerns

This update comes amid scrutiny of Google's new ad tracking policy, which uses IP addresses for user fingerprinting. The U.K. Information Commissioner's Office criticized these practices, emphasizing the need for transparency and user consent under data protection laws.
