I do the same thing (and by default each new tab opens in a new temporary container). I use Tree Style Tabs to be able to organize them. It's particularly nice with a wide-screen monitor, since vertical space is at a premium but there's extra horizontal space. It just makes more sense to use that for the tab bar. I do have userChrome.css to hide the main tab bar though.
