I mean this in the best possible way, but Mozilla -- more often that not -- tends to go along with Google's direction with regard to web platform APIs, supported file formats, etc. In my recollection, their most high-profile disagreement was over WebSQL vs IndexedDB, where IndexedDB was championed by Mozilla with fervor I have rarely seen -- or rather, Mozilla straight-up declared they would never support WebSQL -- and in the end IndexedDB actually won out. There seems to be a general mutual reciprocity [1] between the Chrome and Firefox teams, although in a mercantilist sense of Chrome introducing all sorts of stuff all the time, and Firefox implements them also within a few versions.
