Mozilla is competing for the same talent as Google, Microsoft, and Apple. Browsers are the most important software at those companies because most other software runs on them.
The Hacker News community doesn’t seem to appreciate the work Mozilla has done to establish web standards. I’ve experienced what it’s like to be stuck with IE6 and IE11 for a decade, holding back web projects at work. Firefox broke through that inertia and made Google, Amazon, Netflix and other companies possible. Essentially, Firefox made the whole “startup” wave Hacker News rides on possible (though much of that momentum transferred to the App Stores).
