There’s a beta version of Microsoft’s forthcoming Internet Explorer 8 web browser now available for download over on Microsoft.com if you’re interested. Most of the new stuff seems to center around right-click context menus. One such feature is called “Activities” which allows you to right-click on something to look up information about it or share it on Facebook, submit it to Digg, etc.

There’s also an interesting feature called “Slices” that “enables users to subscribe to content directly within a webpage.” You basically carve out a particular section of a web page you like and can then access just that portion of the site via an overlay that pops up from your Favorites bar. It basically creates what behaves like an iFrame of, say, just your Wall on Facebook that you can access very quickly and easily.
