What browser are you using? [poll]

I still use IE7 because some websites work correctly only with it, and Opera is my backup option, just in case. I find the interface of IE more convenient, so I continue to use it. I even participated in discussions in this thread for some time :) But that was a long time ago, and I think I've become wiser since then. The funny thing is that I consider Firefox to be the best browser – ultimately, it's more stable than both IE and Opera.
