Could you possibly debug this to determine what the texture internalFormat is at the failure? Or try Mesa from git? I can improve the warning message for this problem for the future.
Not sure what driver you're using... I was not able to reproduce this on my Intel Sandybridge system, using either the latest Mesa 7.11 branch (from git, not the release) or Mesa master. I'm also using Firefox 7.0.1 on Arch Linux.
@ Kenneth Graunke Hmm, this is not really critical, but, perhaps the site in question uses features (stuff) that makes Firefox trip, somehow. What do I enter where so you can get more info (if needed)...
Posting the output of 'glxinfo' would be a good start.

It also happens to me with mesa 7.11.2 same glxinfo as Thor's https://bugs.archlinux.org/task/27573

This hardware cannot possibly handle it. At all. WebGL requires either OpenGL ES 2.0 or desktop GL with ARB_fragment_shader. As you can see from the glxinfo output, this hardware has none of the above.
OK, indeed we should not attempt to do WebGL on OpenGL 1. But the stack trace in https://bugzilla.mozilla.org/show_bug.cgi?id=696636#c11 also shows that there is a driver bug here.
Alright, patch under review @moz to block opengl 1.

Agreed. By the time that stacktrace was taken, the underlying bug had done its damage. That's why I asked (comment #11) for an additional backtrace from _mesa_problem. Something is causing the driver to create a DEPTH_COMPONENT24 texture, but that hardware doesn't support depth textures at all. As a result, by the time execution gets to _mesa_get_format_bytes or intel_region_alloc, it's passing around garbage data. In the intel_region_alloc case, the texture format is unknown to the driver, so cpp is zero. The divide by cpp causes the SIGFPE.

Ian Romanick, I am not sure how to do the breakpoint. I did a backtrace, but I don't know if it is useful.

On your 865G system, glx is saying that GL_ARB_depth_texture is not supported. That's why we're failing in _mesa_choose_tex_format(). Evidently, the driver doesn't support depth textures for your older GPU.
