Firefox does start, but I also see lots of those messages you talk about below.

I did a Google search on "Crash Annotation GraphicsCriticalError: |[0][GFX1]: 
Unknown image format 0" and got lots of interesting, and likely relevant hits.  
There seems to have been a problem for big endian systems.

This one actually references a fix:

Hopefully technical support can use these to help out.  Just FYI, depending on 
exactly what you're doing and what sort of browser support is needed, the w3m 
text-only web browser might be all that you need.  There's no Javascript, or 
Java support, for example, but if all you need is basic HTTP/HTTPS function, it 
works quite well.
