Firefox was big because the alternative was dysfunctional. Mozilla cannot really competitively compete with Chrome on features, not for long. Anything new they put out that can pull in a meaningful usershare increase will be replicated by Google. And all the niche features they want to push (privacy et al) aren't going to cause major market swings. Firefox circa 2004 was dominating because IE was a steaming pile of garbage and Apple had no market share at the time. If you wanted a usable browser it was your only option and even then they were still a minority to the installed by default broken trash.
