Sadly Google is single-handedly funding the two of the three largest browser engines. Why Googles motive may not align with mine, I don't blame them, I blame Mozilla leadership for not taking action earlier, and for only half-heartedly attempting to build new revenue sources.
More and more I think that Mozilla should have taken the Google money and created a fund, like Wikimedia. Yeah, yeah, I know, spending donations stupidly, using money on unrelated projects, the point is that they have a plan, and funding to keep running Wikipedia long into the future. Had Mozilla focused on Firefox, Thunderbird and MDN, then I can't see that they couldn't have had a substantial thrust setup by now. Perhaps that would also have allowed them to push a bit harder on donations, but they seem to busy pretending to be a Silicon Valley type business.
I'd be incredibly sad if Mozilla / Firefox fails. I still want Opera to return in it's none Chinese form, using it's own rendering engine. Without Presto Opera seems fairly pointless.
Sorry, didn't realise that fund doesn't exactly translate directly. The Wikimedia Foundation have financial endowment set up, to ensure future funding. My question is why Mozilla doesn't have that? Perhaps they do, but then finding information about it is rather difficult.
