I believe the Firefox development organization could be a lot leaner, and not all of the work has to be directly salaried. There are plenty of huge open source projects that are progressing fine without being run by a single for-profit company. E.g. the Apache ecosystem, the Linux foundation projects, FreeBSD, etc.
I think such projects don’t exist precisely because Mozilla is still developing it. If Mozilla abandons Firefox then someone else will take up the torch.
