I have been experiencing crashes lately with FF8/9 and Blender. Basically, with both open either Blender will crash or Firefox will at some point. My inclination is that there’s a conflict with opengl.
This is a Firefox problem, since I do not experience any problems with other apps with opengl viewports. For example, working simultaneously in Lightwave, Blender and Accutrans causes no issues at all - only FF wreaks havoc.
I suppose I should post this on the mozilla forum, but I would like to know if other Blender users have experienced similar problems with opengl-accelerated Firefox? FF9 seems much worse than FF8 in this respect (which also caused intermittent crashing of Blender)
For system specs, refer to my sig.
