GoKawiilFirefox for iOS Adds Built-In Ad Blocker Using WebKit and EasyList
Mozilla has launched a native Ad Blocker feature for Firefox on iOS that blocks many third-party ads and ad-related trackers before they load. The feature relies on Apple's WebKit Content Blocker technology and the EasyList filter list, and is disabled by default, requiring users to enable it through Settings > Browsing > Ad Blocker.
GoKawiil's interpretation of the reporting above, not reported fact.
Because iOS restricts browser extensions, Firefox previously couldn't offer the same ad-blocking flexibility available on desktop and Android, leaving iOS users with fewer options for controlling their browsing experience. By baking ad blocking directly into the browser, Mozilla addresses this platform limitation while still allowing site-served ads and search ads through, preserving some revenue pathways for publishers.
- Ad Blocker is a native iOS feature, not a separate extension, built on WebKit Content Blocker and EasyList.
- It's off by default, giving users explicit choice over whether to enable it.
- Site-served ads, search ads, and Firefox's own sponsored content remain unaffected by this blocker.
Apple iPhone 16 — Firefox's new iOS Ad Blocker runs on Apple's WebKit content blocking, so it shines on a current iPhone with plenty of screen space for clutter-free browsing. The iPhone 16 gives you a bright, roomy display to enjoy pages once the pop-ups and trackers are stripped away.
