Firefox 4, after what seems like an eternity has finally been released. It has a cleaner look, tabs on top, and is packed with performance enhancements. I’ve been using the last few betas and the RC releases, and have been satisfied with the updates. It definitely feels more responsive than previous versions, although I’d say that Chrome and maybe even IE 9, covered here, are a bit faster in terms of load times. If you’re a FF diehard, there’s no reason not to go upgrade right now, it’s a definite improvement. If you’re entrenched as a Chrome or IE user, I don’t know if there is much to win you over.
