It doesn't ignore the blur: it blurs, but the edges don't become transparent because Firefox uses `edgeMode="duplicate"` behavior by default. It's easier to see that Firefox blurs if you give the gradient a hard edge, for example by putting both color stops at offset 0.5. (Firefox unfortunately doesn't support the edgeMode attribute on feGaussianBlur so you can't choose a different edgeMode... there was some work done on this four years ago in [bug 1094305](https://bugzilla.mozilla.org/show_bug.cgi?id=1094305) but it stalled because of lack of clarity in the spec.)
