Security and Privacy
Edge offers significant security advantages over IE. Like Chrome, it runs in a sandbox, just as every modern Windows Store app does. This means browser processes are isolated from the rest of the system, so site code can't mess with the rest of your PC's operation and other programs. It also maintains IE's SmartScreen Filter, which blocks known malware-harboring sites and flags suspicious downloads. Also, by simply omitting ActiveX, VBScript, and Browser Helper Objects, it gives hackers less opportunity to wreak havoc.
The 64-bit version of Edge is the only one allowed on 64-bit PCs (most, these days), and that provides better security due to a much larger address space for Address Space Layout Randomization (ASLR
). Chrome and Firefox, by contrast, are still installed as 32-bit applications by default.
Unfortunately, Edge dispenses with IE's Tracking Protection feature, which prevented unwanted sites from sharing your browsing information with other sites. The lack of extension support probably explains this, and we may see the feature reinstated in updates.

The Edge in Web Browsing?
Microsoft's new browser is refreshing in many ways. It's drastically faster and more compliant with modern Web standards than its predecessor, Internet Explorer. And by some measures Microsoft Edge is faster and safer than Chrome and Firefox. But it's still slightly behind on new Web standards support, and it lacks the extra goodies that those more-mature pieces of software offer. For a full-featured, fast-performing, and extensible Web browser, our Editors' Choice is Mozilla Firefox.
