Looks like Microsoft is inching closer to releasing the Microsoft Edge browser with extensions to Insiders. In a web page captured and tweeted by @h0x0d aka WalkingCat you can see the early mockups of the extensions including two that look to be available immediately including one for Pinterest and RES or 'Reddit Enhancement Suite' that greatly improves the usage of the Reddit website.
Microsoft originally planned to have browser extensions for the November update, but they were pushed back until 'early 2016'. Windows Insiders will be the first to get the new feature to put it through its paces before going wide to the general public.
Although Windows Phone is not currently slated for extensions, the Microsoft team is reportedly exploring the idea as a "long-term goal."
The extensions for Edge can be natively written or ported over from Chrome using some simple tools. Eventually, the extensions should be featured in the Windows Store too for easy installation, although initially it looks like a manual job for Insiders. More details about the extensions and rollout are expected in the coming weeks.
WalkingCat evidently compared the Edge extensions with the Chrome ones and found that the only difference was " basically substitute "chrome" with "msBrowser", add few minor changes, done." That suggests there should be little problem with getting Edge up to speed with Chrome in terms of extension support across the board.
Currently, the original page where the images were hosted is now reporting back a 403 Error.
