The comments on that site are sickening. Yes, I do not agree with Eich's views. Mozilla owned up to it. Someone should tell them to disable JS everywhere because of Eich. Plus, Firefox is a community project with more momentum than almost any FOSS project. It won't die. edit: read that in reverse
I don't believe Firefox will ever gain marketshare again but Mozilla still has some time to come up with another bread winner before they've lost relevance. They got some serious technology in the works with Servo and there is still lots room to improve browsing on mobile for those that are paying attention.
