Opera still has some issues with java based secure sites, I used to be exclusively Opera since I'm so used to using mouse gestures... But there aren't any plug-ins for Yahoo Toolbar for it and that kinda prompted me to go Firefox... and now FF has color management, so I'm kinda sticking to it now..

I still like Opera's simplicity, though...

IE I only touch for intranet stuff since they're ran off IE's security grr.
