I can confirm. In my experience on edge-case hardware, a raspberry pi 2, Chrome will play 1080p video while Firefox will stutter. And since raspberry pi's are treated as TVs, I get absolutely drowned in ads on Chrome. To be fair, on my other machines I rarely see any ads(ad blockers), so to have my video interrupted by an ad on youtube is way beyond acceptable.

I am now using screen mirroring software "moonlight" to mirror my PC to the TV pi. I find people who watch ads weak minded apologists. Which is also the reason I will never again use Chrome.
