Can you retry in today's nightly build?

It has an important optimization in webgl.drawElements.
(Beta 10 does not have it, but beta 11 will)

ok.
Since we are talking about a performance issue here, the most useful thing to
do would be to run this in a profiler.
Is this WebGL code using vertex attrib 0 array disabled? That would be
something to avoid anyway, as it forces implementation to use costly emulation
tricks (since that is not allowed on desktop OpenGL). Different browsers have
different approaches there, so Firefox could be more severely performance
affected, but still, you don't want to do WebGL rendering with vertex attrib 0
array disabled. If that is the cause of the slowness, then profiles will show
DoFakeVertexAttrib0.
