Microsoft is working to build ad blocking into the “next” version of Microsoft Edge, according to a report. A slide was presented by Microsoft executives. “Build ad blocking features into the browser” is “targeted for the next version” of the browser, version 4682811.

When and if it arrives, ad blocking inside Microsoft Edge would make it the second major browser to natively kill ads; Opera is testing a developer version of its browser that does the same thing. Other browsers have flirted with native ad blocking, including Samsung’s native Web browser for Android. Most of the remainder, including Apple’s Safari and Google Chrome, enable ad blocking through the use of plugins, which companies like Opera say is less effective than blocking them natively.

Microsoft didn’t say exactly when the new versions of Edge will debut with ad blocking built in. Microsoft has said previously that it has begun seeding the Edge browser, with just a few supported extensions, to its Insider group of beta testers.
