I have contributed to both Firefox and chrome, and the amount of legacy code in Firefox makes it so arcane & recondite. They haven't even upgraded jsm, xpcom etc.. And if you apply your logic to chromium. It is being forked and there are many browser like Vivaldi, Brave, Edge etc.. Open Source is definitely not an empty slogan. If there is product A and B, people will choose A if A is better, easier to maintain and popular.
