Microsoft's own Joe Belfiore just unveiled the company's successor to Internet Explorer, Microsoft Edge, and he showed how the browser is another extension of Redmond's cross-platform ambitions. Similar to how Windows 10 supports code from Android and iOS, Edge supports browser extensions from Chrome and Firefox.
With Internet Explorer in the rearview, Microsoft clearly has its sights on the two browsers that users generally rely on, while also focusing on productivity. Belfiore said onstage that Edge is "a browser that end users will think about for getting things done." Pulling that off means building in support for the extensions users already use, but modified with Edge functionality. Extensions will live in the browser toolbar. However, it's still unclear how users can install these extensions.
