Only 3 options on rightclick is very little. Hopefully more options in the future. Waiting for extensions. When they arrive I might ditch Firefox as my main browser. Untill then I stick with Fx 64 bit beta's.
Hi there. There won't be extensions in Edge for it is a WinRT app as with the immersive IE we saw in 8/8.1. Here's some proof in it's development as per Gabe Aul.

Object RTC in Microsoft Edge: For developers, this build also includes a preview of Object RTC in Microsoft Edge. The ORTC APIs enable real-time audio and video communications directly inside Microsoft Edge without the need to install any plugins. You can learn more about how ORTC will work with Skype and Skype for Business over at the Skype blog, and developers can learn more about using these APIs at the Microsoft Edge Dev Blog.
