Firefox loses, because they are doing barely anything to be better than chrome. Brave, Opera, Vivaldi, they all build and sell their own unique identity and seem to be successful enough with it. But Firefox? Basically just exists. Something about privacy and not being the big kraken, but so are all other now too. In the meanwhile Mozilla is just continuing wasting money on pointless projects which do nothing to solidify their cash cows future, while adding nothing of worth.

Yes, the default Browser wins (which BTW is not always Chrome), and Mozilla does not put up a fight to change it.
