Just a note to verify other results. I am having what appears to be the same issue on a AMD64 with NVIDIA GeForce 7025 Video. When I was running firefox from the console (which uses the NVIDIA drivers I downloaded from NVIDIA), firefox ran fine. When I ran firefox while using vnc (which was using the open source driver), it seg faulted on start. Changing the theme to "clearlooks" stops the seg fault.
