//Edge is said to be faster than Internet Explorer. Plus, it has a lot of upgraded features that will surely satisfy developers and general users all the same.
Microsoft's new browser has a built-in notation tool that is integrated with Cortana. Hence, users will be given more personalised results whenever they use Edge.
Unlike its predecessor, Edge supports Chrome and Firefox extensions, enabling users to carry their favorite plug-ins to this new browser.//
Edge is not the 'new name' for IE. It is a whole new operating system independent of IE, which we all knew was out of date 10 yrs ago. IE will rightly be binned in the near future. Plus the new sandbox system Defender security that is with Edge is really quite good.
