Support for VAAPI decoding is still in development:
An action by the iHD driver is blocked by the content process sandbox.
bug 1595994 will move VAAPI decoding over to the media process and bug 1619585 comment 17 will add a sandbox exception.

You can either disable the sandbox (security.sandbox.content.level=0) which is insecure or simply start Firefox with this env var:
LIBVA_DRIVER_NAME=i965.
