ZDNet writer Mary Jo Foley spotted that Microsoft's Russian press website accidentally published a screenshot of what appears to be Internet Explorer 9 beta.
By running the Russian text through a translator, she found out that Microsoft's upcoming browser will feature provisions for "recognized" or "protected" sites that will enable you to go straight to these sites from the Windows taskbar without having to open IE first, and she also discovered that IE9 will get support for tear-off tabs, which will enable you to snap tabs to the side of your screen, just as in Firefox and Safari.
Microsoft is also focusing on cleaning up the user interface, all menus will be consolidated into one, and there will be a combined address/search bar. More info can be found over here.
The Russian Microsoft site said that there will be provisions for “recognized,” or “protected,” sites which will allow users to go straight from the Windows taskbar to these sites without having to open IE first. In other words, recognized, protected sites will be treated more like traditional Windows applications.
Bing translated the instructions for doing this as “(C)lick the pins in the address bar or click the site in a new tab and drag it to the taskbar. That’s all. If the site is pinned, it displays an icon that is separate from the Internet Explorer. Now from the website you are just one click.”
(It sounds like this might be a feature accessible by Windows 7 users only, though I am not sure.)
