I think that I'm rather observing than accusing. Which of my statements do you need evidence for? That Mozilla fumbled despite Firefox having 30% of the browser market share? See its market share today. That they played wallflower while others were figuring out the front-end ecosystem? See the ensuing decade of front-end tooling extravaganza, through which Firefox's role was reduced to the app that eventually runs your web app (i.e. you the community figure it all out). That Firefox was an undervalued asset? See their foray into other venues, despite Firefox's untapped potential in being a real platform for the web (unlike Android and iOS). That Mozilla didn't see Firefox as their Trojan horse to share the apps market pie? See their equivalent of the App Store and Google Play. That they sat on it to barely make it compete with Chrome? Firefox has been my primary browser since it was still named Firebird, there was an extended stretch during which my faithfulness had nothing to do with it offering a better experience than Chrome. Indeed, even today, I still have to start Chrome from time to time for a few things that FF doesn't handle well.
