They could just take that $400 mil/year and dump it entirely into the browser for as long as the money lasts. Ideally spending some money refactoring their codebase such that it could be more likely for the code to survive on after a loss of funding as an non-Mozilla open-source project. Follow the public radio route and take donations, build a sense of community.

Sorry Thunderbird lovers :P)
