> How about Firefox getting rid of their main source of revenue.
FTFY
So it is okay to promote Google just because it makes them money? That is what allows Google to stay at the top. Why not ask FireFox users to donate a little money to fund development?
As much as I pay for services I use, many people don't have the ability or won't see it as important enough to fund. While you and I might see the purpose, I suspect those like us area in the minority.
I think that would be end of Firefox. Google pays Mozilla to have their search engine being default in Firefox.
