I normally have 2–3 browser windows open with at most 5 tabs each. I find that the window → tab hierarchy works very well with my workflow and it allows me to close tabs aggressively when I don't need them without being complex like TreeStyleTabs. For example, if I'm looking for reference on a particular function I open a new window, open tabs for a couple of relevant results, do some research, and when I'm done I just close the window with all the tabs in it. I just don't understand people who have a million tabs open in a single window. You clearly don't remember what's on each tab, so it's just screen and mental real estate being used for nothing. For a Mac, I found that Hyperswitch works really great for letting Command+tab choose the correct window instead of doing the unexplainable mess of OSX application and window switching.
