The i3 window manager and a full-screen browser on one display works really well, in my experience. Shuffling it or other things to the other display is easy, as well. I'd liked the idea of tiling WMs, but the ones I tried all seemed clumsy until I happened upon i3, and it was like coming home: 90% of the defaults were exactly what I would have picked, and all the others were easily configurable in a text file.
