Reportedly, internal testers of the Edge browser spotted a big change in the Canary version of the Android version. This version adds a new flag to enable the extension function of Edge for Android.
Users can enter “edge://flags” in the address bar of the Android version of Edge Canary and will find a flag named “#edge-extensions-android”, whose description is: “After enabling, users can Enable selected extensions.”
There is no information on whether the iOS version of Edge will also add extensions, but it is very likely. In addition, currently, joining the Edge Canary test for iOS can only be done through the TestFlight app with a limited number of seats.
