What a statement. Mozilla going bankrupt would be disastrous, I don't think you appreciate how much effort goes into maintaining and evolving browsers, there are very few entities well funded enough with the expertise to maintain a fork, and that's without making assertions on their altruism. Mozilla's is in the right place, even if far too often they miss the mark.
There's not really a strong incentive to while Mozilla is still around (and despite that, there are still a few forks... Waterfox, for example). I think it would take a collapse of Mozilla, Oracle-style, to really spur that.
(edit: Oracle didn't collapse, I mean what happened to OpenOffice.org.)
Personally I'd vote for Apache, or a new FOSS group. They don't need all the funding that Mozilla currently gets (most of which isn't spent on Firefox anyway).
I'd rather see that effort than something like Ladybird, personally.
Looking at the financial statements for Mozilla and Apache, Apache'a total revenue ($2.3 million)for 2023 is less than 1% of Mozilla's software development costs ($260 million).
Yes, Mozilla is mismanaged, but I'm very doubtful Apache has the resources to continue Firefox development and stay competitive.
