I just killed the horizontal tab bar after installing Tree Style Tabs (it's a quick trip to edit a profile CSS file and is quite well documented on the TST github page). The tree tabs are really all you need.
Tree tabs work just as well with 5 tabs as they do with 50 (or, heck, even 500). I use them as a mix of short-term bookmarks, active browsing contexts, trains of thoughts, etc. It has quite fundamentally changed the way I browse around the Internet, and I can simply never use Chrome or Safari the same way again.
I often similarly need to research some particular thing a bunch. With tree tabs, one parent tab contains the main context, and every time I open a new link in a new window it will appear as a child. In the end it's a big tree of tabs with one root tab, with the tree giving a nice hierarchical organization based around where the tabs came from. TST gives you the ability to group multiple tabs together ("stacking" them), and then you can rename the group and collapse it (or, for more permanence, bookmark the entire tree).
