Reichenstein argues that tabs were a good solution for an earlier age of the Internet, when users hardly ever had more than ten tabs open at any given time. Now, however, as browsers are slowly turning into operating systems, a new paradigm for organizing this information has become necessary.

The current generation of browsers does a decent job when it comes to keeping a current browser session organized, but Reichenstein wants to create a system that structures the browser more like a mutimedia file system. He proposes a new interface that looks more like iTunes than today's Firefox, with folders, libraries, and bookmarks in a sidebar.

Interesting Idea this. Also, dont forget to check out the Tree Tabs addon for firefox, I just installed it and loving it so far!
