Mozilla Firefox is revising its Referrer Policy to include extra protections for user information, ZDNet reports. Firefox 87 will include a “stricter, more privacy-preserving default,” Developer Dimi Lee and Security Infrastructure Engineering Manager Christoph Kerschbaumer wrote in a blog post. The changes will “prevent sites from accidentally leaking sensitive user data,” they wrote, adding Firefox 87 will provide “a significantly more private browsing experience.”
