The hardest thing to see here is that we don't have a solution. Firefox makes money by setting google as the default search. Google is its biggest competitor. There are no obvious other revenue stream. Also, let's not pretend chrome sucks. Chrome is on top because it is an amazing browser (and you are googling stuff anyway).

Firefox needs to change it's strategy, it needs to pull an Amazon.

Amazon is the type of business that cannot be built. It costs too much, it was not profitable, but it was a stepping stone. Amazon sold books to get people in, built AWS (a separate business) to fund the business, created a fast delivery network (also funded by AWS), and then became profitable.

Firefox needs to find it's AWS if it wants to survive.
