Firefox 151 packs big privacy upgrades into a small update

Mozilla has published release notes for Firefox browser version 151.0, and this update includes several genuinely meaningful privacy and security improvements. Three changes stand out in particular: Stronger anti‑fingerprinting Broader protection for local network access More control over private sessions and permissions Note that Mozilla says several Firefox 151 features are “part of a progressive roll out,” meaning they will appear for some users first and be expanded over time.
