The only time I have more than 2-3 tabs open is when I open a bunch of articles at the same time (like on HN), to read through one-by-one, closing them as I go along.
How do you keep track of all those tabs? Why not just use bookmarks, open what you're interested in, and then close it?
I'm sincerely interested in this from a UI point of view...
And if your interest is speed in visualization, if the answer isn't a special list of sites that browsers might pre-render in the background, so your favorite sites always "loaded" instantly?
Admittedly this is probably a strange way of working with the web, but I like to be able to easily find things that I've been working on recently. Only at the end of the day do I fully scan through my tabs and bookmark anything I'll need to reference later.
I also think this has a lot to do with browsing style as well. For purposes like my own I rarely need to have more than 5-10 pages actively open. I make extensive use of bookmarks and generally group my tabs in separate windows for organization purposes.
I think I just found an extension that could replace Tree Style Tabs. I was looking for something like this last month didn't see it. This puts the Tab Groups in the sidebar. .

What I like about this extension is that the tree would only allowed to get 1 level deep. With Tree Style Tabs, many tabs I don't want anymore can hide under a top tree node. Also, it looks like it will play well with Tab Mix Plus and I can keep the top tab bar.
