If accurate, the browser would join Opera and other browsers in natively stopping ads. Google has abstained so far with its mobile version of Chrome (for five billion reasons), though you can install third-party ad blockers on Chrome desktop. While users may enjoy extra data-savings, security and speed using such apps, publishers that rely on ad revenue are revolting. Sites like Forbes won't even let you browse without turning off your adblocker and in France, multiple news sites have banded together to curtail them.

Microsoft didn't say how its tech would work or when, exactly, the next Edge version will come. If its figures on Windows 10 adoption are accurate, however, a larger number of folks would suddenly get access to ad blocking tech. That could change the equation for publishers and ad networks (like Engadget's parent AOL) significantly.

Update, 3/31 3:30PM ET: Since this post was published, Microsoft clarified that it will not be offering built-in ad-blocking. It will support new extensions for Adblock and Adblock Plus, but Edge won't have ad-blocking features in its default configuration.
