IE8 Color Coded Tabs

I spent today reading some articles on internet browsers, their features, and their programming models. 

Processes are the New Threads:  One of new approaches many browsers are taking is to model tabs as processes instead of threads.  Why?  Crash Protection.  When a tab crashes, it will only crash that specific tab instead of all tabs you have open in your browser.  Scott Hanselman provides a great overview on his blog.

Reading this article on internet browsers, I discovered a cool IE8 Feature that I hadn’t noticed before. 

“Has Maximum PC gone toxic? No! Those green tabs are part of IE8's new tab grouping feature called Groups. Opening new tabs from within an existing one places them all next to each other in a color-coded group. You can then ungroup individual tabs, close out an entire group, or move tabs from one group to another.”

I’m mixed on the article itself, it doesn’t give you perspective on whether two browsers support similar functionality.
