Microsoft is rolling out a new update to its Edge browser on iOS, and it brings a couple of important features. First, users can now choose whether to sync their browsing data with Microsoft Edge Legacy (the UWP version) or the new Chromium-based version of the browser.
The other notable addition is a new tracking prevention setting, which has already been present in the desktop version of the browser for a while. Tracking prevention prevents websites and companies form following users' activities throughout the web, which is a common method used to deliver targeted advertising. Edge offers three settings - Basic, Balanced, and Strict, which offer varying degrees of protection. The Strict setting can cause some websites to break, though.
The mobile versions of Edge do include some built-in extensions, including AdBlock Plus, so this tracking prevention setting isn't necessary if you want to stop ads from showing up. It could be, however, a more native way to do it, and give you some control over the aggressiveness of your tracking prevention settings.
The feature doesn't seem to be available on the Android version of the browser yet, but it would make sense for it to make its way there eventually. If you haven't yet, you can get Edge for iOS from the App Store.
