It may kill Mozilla, no reason to say it will kill Firefox itself. Perhaps Firefox would flourish a lot more if it is finally released from Mozilla's clutches.

Yes, I should give up my country and the rule of law to preserve firefox, Google's little bodyguard.

TLDR: Mozilla makes money from Google paying it to be the default search engine on Firefox. If that practice is outlawed, Mozilla will not have any income stream even close to replacing that.
