It's not true, Mozilla actually tried to block them by default back in 2013 but was threatened by the ad industry and backed down. http://www.computerworld.com/article/2495739/internet/ad-ind...

I think it was mistaken for Google paying Mozilla to keep it as default search engine.

And yet desktop Safari continues to block most third-party cookies, last I checked.
