Mozilla's recent privacy policy changes have left many Firefox users concerned about data collection and privacy practices in their once-trusted browser. The company's February 2025 update introduced new Terms of Use that grant Mozilla broader control over user data, marking a significant shift from its historically privacy-focused approach.
The new policy allows Mozilla a "nonexclusive, royalty-free, worldwide license" to use information entered through Firefox. This change, combined with the removal of previous privacy commitments from their FAQ, has sparked worry among users about potential data sharing with advertisers or AI training models.
While Mozilla's VP of Product Management Ajit Varma maintains that the company doesn't sell user data, the revised language and Mozilla's venture into AI through Mozilla.ai has left many users skeptical. The arrival of executives from profit-driven companies like Meta has further fueled these concerns.
For users looking to enhance their privacy while using Firefox, here are key steps you can take:
Lock Down Your Internet Enable DNS-over-HTTPS to encrypt your DNS requests and protect your browsing habits from ISPs and other third parties.
Consider Alternative Browsers Privacy-focused options include:
- Brave (Chromium-based)
- Waterfox
- LibreWolf
- Zen Browser (beta)
- Tor Browser
Strengthen Firefox Privacy Settings
- Set Enhanced Tracking Protection to "Strict" mode
- Switch to DuckDuckGo as your default search engine
- Disable Firefox data collection features
- Enable Global Privacy Control
- Configure content blocking for cookies, tracking content, cryptominers, and fingerprinters
Managing Expectations While these measures can help protect your privacy, users should understand that today's Firefox operates differently from its previous versions. The browser that once championed user privacy by default now requires more active management from users to maintain strong privacy protection.
The changes reflect a broader shift in Mozilla's approach, suggesting users should remain vigilant about their privacy settings and consider their comfort level with the new policies.
