Firefox for iOS Gets Built-In Ad Blocker

Mozilla today said it is adding an ad blocker to Firefox for iOS, allowing users to block many third-party ads and ad-related trackers. The ad blocker uses the EasyList filter list and Apple's WebKit Content Blocker technology, which is the same content-blocker API Safari ad blockers use. App Store ad blockers only work with Safari, so Mozilla built the feature directly into the app.
