If a browser fails in some key function even 1% of the time that's enough to drive most users from Firefox to Chrome. To win back market share Firefox has to be much, much better than Chrome. That's how Firefox won market share from IE in the 2000s and how Chrome won in the 2010s. Firefox feels ever-so-slightly slower to me on loading most web pages and has more failures in loading page elements that I notice than Chrome. "Just works, most of the time" isn't just works. Just works is perfection or as close to it as software can get.
