The one thing that could save it, Servo, doesn't seem to be a priority. Instead, Mozilla seems to be focusing on offering cloud services that nobody wants or cares about, which also don't really respect privacy any more than other cloud services. The only significant revenue stream Mozilla has is through Firefox, which keeps steadily losing users and market share.
And even that is almost entirely dependent on people using Google search with the browser. Given that Google is Mozilla's primary competitor who has intentionally broken their apps on Firefox and is pushing them down in search results, and that Firefox is marketing itself to privacy-conscious people who wouldn't use Google anyway, it doesn't seem wise or sustainable at all.
Unless things seriously change, I have no faith that they'll be able to turn this situation around. We may just have to live with a Blink/WebKit web monoculture until we get some serious anti-trust legislation.
