Thanks, Greg, for the explanation on VAAPI use. It's still a bit confusing.
Does this mean that building mesa with VAAPI enabled is meaningless for

As far as firefox is concerned, I tried running it with the "MOZ" variables

also looked though about:config for relevant settings, but came up blank.
