You should actually read the link you posted. That had nothing to do with Firefox and has everything to do with ad blockers. Looks like YouTubes goal was to bring parity between those using ad blockers and those not, as to not incentivize ad blocker usage, not to cripple Firefox.
And ? It is part of the anti-adblocker code which is clearly targeted at Firefox. What sort of extra-ordinary bar are you keeping for malice if not this ?
