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. Firefox won't block ads served by the site you're visiting, and ads shown in search results will still appear. Sponsored shortcuts and other sponsored content shown by Firefox when you open a new tab are separate from ads and won't be blocked. Ad blocking is turned off by default, and it can be turned on in the Firefox app by going to Settings > Browsing > Ad Blocker.
