Mozilla lost because they sat on their butts for 10 years under Eich and lost their technical advantage. Firefox got sandbox and multi-process features in 2016 that IE8 had in 2009, they were happy to crash and lose every Pwn2Own before that. Being semi-nonprofit they can't secure any talent so they fake being like Google by blowing money on social activism and rebranding when they're not siphoning it to buy each other's start-ups.
