Firefox for iPhone Adds Optional Built-In Ad Blocking and Tracker Protection
Brief
Mozilla has introduced an optional built-in Ad Blocker for Firefox on iOS, giving iPhone users a native way to reduce third-party advertising and related tracking activity while browsing.
The feature, announced on September 1, 2026, is disabled by default and can be enabled through Firefox’s settings.
The addition addresses a common mobile browsing problem: advertisements, pop-ups, overlays, and tracking scripts can consume limited screen space, slow page rendering, and interrupt access to content.
