Great Firefox Tips/Hacks
If you're not using Firefox, you're really missing out. Here's a great K5 run-down that lists some great hacks and plugins you can install on it to make it work exactly how you want it to (there were several plugins on there that I have never heard of, but now have installed). The coolest thing I hadn't seen before are these performance-tuned builds of Mozilla products that take advantage of the extra instructions on modern processors. I've installed one of them, and it works pretty slick.
And I don't care how fancy IE 7.0 is supposed to be, I doubt I'll install it (actually, I will, but only for testing purposes).
