Five years ago it was clear that possibly the best thing that could happened to the future of Firefox, Mozilla, and the Web would have been for Mozilla Corporation to have gone belly up. But we're past the point where that might do any good with respect to salvaging Firefox or Mozilla's name.
Mozilla Corporation's role today is to siphon away any attention or enthusiasm that might otherwise be directed towards the ideals that Mozilla was originally created to facilitate. The Mozilla Corporation was supposed to have been set up to further the ideals of the then already extant movement that had been operating on a shoestring budget. The imprimatur should have been to direct its paid staff towards doing the boring work that unpaid (but highly effective) volunteers weren't interested in—not to wrench control away and consolidate power within a (now-proven ineffectual) company making ill-conceived commercial plays while trying to fit in with the culture of the Valley and squandering billions.
In the early 2010s, I attended a conference—one sponsored by Mozilla—and brought in on their dime, having been a fairly involved contributor for a few years, but not someone on the corporate payroll. Another guest and I mentioned how poor a job the travel agency had done, essentially fleecing Mozilla and doing much worse than if we'd arranged for travel and accommodation ourselves and then forwarded the bill. "Mozilla has a lot of money" was the response. After the better part of a decade, Mozilla's revenue has only grown, and so has their propensity to squander money.
The best option we have now is for folks to wake the heck up, to realize that the Mozilla that exists is not the one portrayed in either its messaging or fixed in the minds of casual slacktivists, to start a grassroots effort (a la early Firefox) to work on an independent browser—where, unfortunately, the best bet at this point is probably in leveraging WebKit against Chrome and Blink, given what an untameable mess the modern Web has become (not helped by the FirefoxOS efforts; nor the mess that Gecko codebase has become)—and most importantly never allow that effort to be subverted in the way that the Corporation managed to cannibalize and take over Mozilla.
But that's not going to happen, because Mozilla continues to position itself as the organization where folks with a casual interest in the health of the Web are supposed to direct their good vibes, while thoroughly proving itself to be unworthy and incompetent at upholding the principles it's supposed to be fighting for, and while time and time again, the public have proven themselves to have short attention spans on the order of months—so, by the end of the year Firefox and Mozilla will be back to being perceived as your old chum that's fighting the good fight, instead of being steered by a bunch of clueless, well-salaried Bay Area devs LARPing as some motley crew with your best interests at heart, all while the term "non-profit" gets bandied about in public discussions, much to their delight.
