Ah I see, I thought the parent poster meant malice on the part of Mozilla, got confused by bouncing between comment threads. I could see malice, since it is Microsoft, but what's the "why" of it? I don't really see any motivation that M$ would have to block Mozilla, all it's going to do is piss off users. It's not like people are gonna get fed up and switch to Edge, they'll get fed up and switch to Chrome. If anything, M$ has a great incentive to improve Firefox adoption. The market that uses FF is the same market that is never going to choose Edge. FF and Edge both have a much better position if they can damage Chrome's market share.
