Firefox can always compete, because if it ever stopped existing Google would have an antitrust case on their hands. For the same reason, Google cannot violate web standards, like what has happened in previous browser wars.

I don’t agree that Firefox is unable to render a portion of the web, I’ve been using it for years and have never once run into a website that had a problem with my browser. I thought once that studentaid.gov did, but that turned out to be a problem with extensions. I’ve seen more websites that have issues with me using Linux than with Firefox.
