Must mention this - the new version of Mozilla Firefox launched yesterday or the day before. If you're not using it, go and get it here. In my not so humble opinion, it's the bestest web browser ever. I've been using it before it was called Firefox, even before it was called Firebird, back in the Phoenix days, and would never, ever go back to IE, which is a bloated, buggy, standards-ignoring pile of shit.
I love Safari on my Powerbook, but I've just downloaded Firefox to use instead, because it just does more things, and I'm used to it. I'll miss Safari, but I miss Firefox too much, with all its little extensions that make life so much easier. Go and download it, you don't know what you're missing.
