im using the FireFox 1.0 preview, and I love it. I was using Avant browser, which ibasically adds a few cool features to IE, and liked that, but page loading times were ridiculous, I have a broadband connection and it was acting slower than diial up, so i grabbed firefox. I had used it before ages ago when it was callled pheonix or firebird or something, and It's definately and improvement. the only thing I wish I could figure out is how to make new pages open in differetn tabs instead of opening a new browser, Avant browser did that and that was my favorite thing about it. I also like the RSS feed bookmarks, or live bookmarks, as firefox calls them, pretty neat feature.
