Firefox and flash content

Factual Questions

I just downloaded Firefox 2.0 (first time Firefox user). When I try watching a YouTube video, I get a message saying

I went to Tools>Options, and both “enable Javascript” and “enable Java” are both checked. So I followed the link to get the Flash Player, but Firefox isn’t on the list of supported browsers.

Obviously I’m doing something wrong… do I have to download an extension to play flash content? TouTube (and others like it) work just fine on IE and Opera on my laptop.

I’ve got Win XP Pro, in case that helps. Any ideas?

I’m an idiot… I have the installer for Opera on my hard drive. I just ran that again, and it works now :smack:

Thanks!
