Have you looked at Tree Style Tabs[1]? I think it fits right in with your characterization of tabs as frozen stacks of information. It takes the concept even further by visualizing the relationship between tabs. I compulsively open stuff in background tabs, and it's very nice to have those tabs as children to the originating tab. In part because it lets me kill a parent tab along with all children, but without affecting anything else, with a few clicks. It also lets me drag a whole thread of tabs to a new window or bookmark it etc. etc. Finally, having a vertical tab list makes efficient use of wide-screen displays and you can still read useful amounts of the page title even with 25+ tabs. Oh and here's another one that might be even more useful to you, with your emphasis on the browser history: Tab History Redux[2]. Tabs opened from links (e.g. via mouse3) retain the history of the originating tab. Yeah. This is one of those things which I can't understand why it hasn't been part of all browsers for years. It just makes sense. Both addons work fine in Firefox Nightly (9) with forced compatibility using the Add-on Comaptibility Reporter[3].
