No this is Google favoring new standards before some browsers are quite ready for it. Firefox supports 60fps if the video is encoded in WebM (VP9) which only happens on Youtube if it has enough views to warrant encoding it in additional formats. Mozilla is still working on Media Source Extensions and MPEG-DASH support which is needed to play back h.264@60fps but afaik it should be in FF36 although it's not ready yet in nightly 36 builds.
Google could have added support in the Flash player but why would they put in the effort for a fairly novel feature when they are trying to replace flash with HTML5? In a few months every browser will support the HTML5 features and nobody will remember this story.
