When switching web browsers, importing favorites isn't hard, but the thought of losing all your extensions is usually what keeps people where they are. As a result, even if you're on Windows 10 already you might not make use of Microsoft's slick new Edge browser until it too has support for add-ons. Unfortunately, in a statement to Ars Technica Microsoft confirmed rumors that its current plan is to put off the addition of extensions until next year. Its decision is apparently based on the need to make sure its extension model is secure before delivering it in a 2016 Windows update. While browser upgrades are still cooking, all signs indicate a fall update is on the way in November withmost of the features currently being beta tested, like an integrated Skype experience, new features for Cortana and an activation process that can accept product keys from earlier versions of Windows.
