In order to get the SVG file to render like the PNG, you need to edit kernelUnitLength from 0.01 to approximately 1.0 (or delete it). Not sure whether something might have changed in how Firefox handles this attribute to cause such a drastic difference.

I should test in a clean profile to see whether I get the same result...

Edit: Same result in a clean profile, i.e., no extensions or settings changes from factory default.
