Sure. But loosing the money to fund development surely won’t help, will it? My point is that there is a real danger here. There are other forces at play which is why you have the chrome dominance already. Long term firefox will fall behind if not maintained. There really needs to be a push to finance firefox or alternatives.
Or imagine if more and more websites “require” some new web protocol to prevent ad blocking, or use of DMCA against browsers or addons altering websites as “web apps”. This is another problem that cannot be solved through individual responsibility.
