Why must Firefox and Opera fight?

Why must we fight?
Can't we at least just put it off until we distroy Internet Explorer?
Come on! Lets team up and distroy the true evil, instead of bickering all the time about which one is better...

Opera only works on platforms that is in Opera's finanical interests to support. (Let's all hear it for FreeBSD Opera that'll still work years from now..) The 'free' has another meaning for Firefox, too. 'Free beer' software like Opera has only ever fucked people over in the long run.
