I do this manually (in FF) with one window per project, and N tabs per window. Works well enough even without extensions.

How do you do the per-window-stuff? Do you use a different firefox profile for each window? And how is it handled if one window is closed?

In this setup you just have to be careful to quit FF rather than close a specific window.
I could do something similar with bookmarks but that would be way slower and not as comfortable.
