Mozilla today released Firefox 11.0 for iOS. The new version turns on tracking protection by default, lets you reorder your tabs, and adds a handful of iPad-specific features. You can download the latest version now from Apple’s App Store.

Mozilla doesn’t break out the exact numbers for Firefox, though the company does say “half a billion people around the world” use the browser. Firefox for iOS was released in November 2015 and has been steadily updated ever since.

Tracking protection means Firefox blocks website elements (ads, analytics trackers, and social share buttons) that could track you while you’re surfing the web. It’s almost like a built-in ad blocker, though it’s really closer to browser add-ons like Ghostery and Privacy Badger because ads that don’t track you are allowed through. The feature’s blocking list, which is based on the tracking protection rules laid out by the anti-tracking startup Disconnect, is published under the General Public License and available on GitHub.

Firefox 9.0 for iOS brought tracking protection to Apple’s mobile operating system in September, but only in Private Browsing mode by default — regular browsing required that users turn it on. This is the same feature that’s available in Firefox for Android, Windows, Mac, and Linux, as well as the same ad blocking technology used in Firefox Focus for Android and iOS.

The difference is that with Firefox for iOS, it’s on by default. And you can turn it off and on for each site (long-press the URL bar and tap the shield icon):

The feature is great for privacy, but it also improves…
