Firefox is a good program. Anything that can break the Internet Exploder hegemony is a good thing.
But I can't figure out for the life of me why it has so much press and support compared to Opera. I can't see a single thing Firefox does well that Opera doesn't do better, other than attract attention. About the only thing is, Firefox's library of plugins includes things Opera's integrated approach doesn't include; but the price of that is instability, and thus not generally worth it. Strip Firefox down to a rich but stable assortment of necessities and luxuries, and you end up with... a poor imitation of Opera. Firefox is like a gangly, clumsy, untrained, but promising teenager, and Opera is the sophisticated, mature, experienced adult it hopes to become one day.
For years, we Opera users have sat quietly, watching the whole world mindlessly glom onto a bit of software that was mediocre at best, unstable at worst. We've been marginalized, and constantly pressured to join the mediocrity by bad web page designers, but we have held out, confident that one day all the bad juju would add up and people would realize what crap their browser software is, realize there's so much better out there, and catch up with us.
So now the masses have realized, but instead of coming to the most mature, best developed, best standards-compliant, and fastest package, they simply went to something less bad. Better than IE, but that's not saying much. They're just repeating their mistake in a lesser amount now, and for no real reason I can see other than the happenstance of press. So instead of being vindicated and, more importantly, finally freed of the pressure to conform with the bad choice of the majority, we're simply pushed into a different margin, forced to still wait for the masses to wake up and do a fair comparison.
What would it take to get people to give Opera a fair shake, anyway?
