Firefox & IE. Although I'll probably be using FF a lot more now because...
Kinda semi-related question: I've been having trouble in IE lately with not being able to directly open anything that's an .mp3, .wav, or .mpeg (like the videos on my own site, for example). Rather than just opening up in another program (Windows Media Player in this case) like they used to, when I click the link I just get a "Page cannot be displayed" error. I can still right click & download, but not just click and open them right through IE. And this happens on every other web site I've tried with the same results. Firefox seems to be okay with all of them though. I've tried Googling for help with this but I think I'm missing the exact technical term for this problem or something.
