After recently installing Mozilla's Firefox on my computer, I can already say I'm impressed. 
I finally decided to download it after wanting to use the Ice 2.0 theme on here, and after it was brought to my attention that it only worked on FF, Darth, Bededog, and dog64 convinced me to make the switch. The layout is a lot cleaner, there are tons of add-ons and themes to use, and it all seems to run smoother than IE 8.
Now, I just hope my dad doesn't kill me for doing it.
