"Unfortunately, that will leave Edge users with virtually no ability to adjust the browser's behavior or add new features. (We're looking at you, AdBlock.) The new browser supports neither ActiveX controls nor Browser Helper Objects (BHOs), which developers could use to extend Internet Explorer with plugins and add-on toolbars, respectively."
But no one needs to use any of these things to block adverts in IE. It has great built in advert filtering which can use the same blocking list as Adblock via the "Tracking Protection" feature. As far as I can see this will still be supported in Microsoft Edge as it does not seem to be on the list of removed features.
