Just last week, the Edge beta on iOS and Android picked up the ability to block ads. Now that that the testing has completed, the same feature is now exiting beta and is rolling out to the general versions of the mobile web browser.
As a recap, this long requested ad block integration is powered by AdBlock Plus, so you might expect the same experience as the extension on Windows 10 PC. Importantly, you don't need to download any extensions for it to work, as Edge on iOS and Android don't support extensions just yet.
You can find the feature by heading to Edge Settings, and then clicking on Content blockers. Of course, you'll have full control of what content can be blocked, and you can turn off the setting for acceptable ads, and whitelist your own websites to support their content (like OnMSFT.) See it in action below.
If you're up and running with version 42.0.2057 on Android, or version 42.2.0 on iOS you should be seeing the feature now. You can download by checking the links below.
