I was expecting this to work with firefox-3.7a2pre and the mentioned options turned on. Unfortunately it doesn't. Even with software renderer turned on, it tries to lookup the mesa library. I tried this using the daily 3.7 build from ubuntu ppa. Has anyone found out how to run it in this setup?
Uh, while Mesa often uses hardware to accelerate rendering, it doesn't have to. It also implements OpenGL in software, so it's not totally surprising that Mozilla needs Mesa to do OpenGL-based rendering.
