FireFox is not as good. It has AdBlockPlus, and that's it. FireFox is overrated.
Safari is impressive as well, but simply not as good.
Internet Explorer is good, albeit not as a good.
Konqueror is a close. Opera is better.
On Opera, you get to install more SKINS, use Speed Dial, OPERA TURBO (WHICH INCREASES SPEED ON THE SLOW NETWORKS), and everything that's so awesome.
Just install Opera 10.10. It's awesome.
