Microsoft announced Project Spartan will be called Microsoft Edge. Joe Belfiore, Microsoft's corporate vice president of the operating systems group, announced the news on stage, adding that Edge will have support for extensions.

He also showed off the new logo which looks so familiar to us it is a wonder why they bothered renaming Internet Exploder in the first place.

Edge will be the new browser shipping on all Windows 10 devices (PCs, tablets, smartphones, and so on). Belfiore explained the name as referring to "being on the edge of consuming and creating" as opposed to being on the edge of a nervous breakdown which typifies our experience with Internet Explorer.

Edge will be the default browser for all Windows 10 devices, with a focus on giving developers a proper experience (no document modes or compatibility views) and offering consumers unique features like the ability to annotate on web pages, distraction-free reading, and Cortana integration.

Developers should be able to take their Chrome extensions or Firefox add-ons and, with "just a few changes," bring them to Microsoft Edge.
