Internet Explorer 10: Touch-Friendly and Securely Sandboxed

By Peter Bright, Ars Technica

Microsoft is continuing to show off new features coming in its Internet Explorer 10 web browser, with a couple of posts describing its touch-friendly Metro interface and its enhanced security.

The current trend in browser design, led by Google Chrome, is to scale back the browsers interface so that it takes less and less of the screen, devoting more room to the web content itself. Windows 8s Metro design similarly removes window chrome to put the focus on content.

Metro Internet Explorer 10 is the logical conclusion of this trend: Most of the time it has no visible interface at all, leaving only the webpage visible. Its app bar, displayed by swiping from the top or bottom of the screen or right clicking the mouse, contains tabs, the address bar, and so on.

The Metro version of Internet Explorer feels slick and comfortable using both touch and mouse and keyboard interaction. Particular highlights are the tile-based favorites view and the tab thumbnails, both shown to good effect in Microsofts post.

Internet Explorer 9 introduced some particularly taskbar-oriented features: support for pinning sites to the taskbar, and the ability for those pinned sites to create custom options in the Jump list. In Windows 8, sites can be pinned to the Start screen to make them instantly accessible. Sites pinned this way can even update their tile to show status notifications much in the way that real apps can do. However, the Jump lists are tucked away, only available from within Internet Explorer.

One concern that this chromeless look raises is that of differentiation; Metro-style versions of both Chrome and Firefox are being developed, and its hard to see how they might look any different.

Security-wise, Internet Explorer 10 will include a new Enhanced Protected Mode. Protected Mode is the name Microsoft gives to its sandboxing technique. The current version, introduced in Internet Explorer 7 on Windows Vista, creates a separate, low-privilege process for running JavaScript and rendering HTML. This low-privilege process has no write access to most of the file system. This means that even if there is a security flaw in the browser, the attacker cannot write malware to the hard disk.
