How would you develop Firefox?
Not being obsessed with rapacious growth, not chasing trends and features that look good on delivery metrics but instead building a stable product would go a long way.
And frankly, for descriptions on what the product should be, standards to implement (or not), and overall strategy for a project that tries to do its best for tech as a whole - Mozillas own writeups are spot-on! They just don't seem to act in accordance with the "vibe" and ideals that blog posts etc. talk about.
Any answer that’s not fully bulletproof immediately rules any other opinions you may hold illegitimate.
