lol I love how everyone is on the Firefox bandwagon. No one can name something about Firefox that another browser hasn't done a lot better. If you want speed and a lightweight browser go with Google Chrome. Google Chrome is 10x better than Firefox. If you want something with pretty cool add-ons Opera is 10x better than Firefox with add ons. If you want a browser that has a decent style layout, Safari beats Firefox with that as well. I would even update your IE to IE8. IE8 is genious with being able to select how you want it to render web pages. Especially if you are browsing older websites you can have it render with IE6 or lower versions of IE. Firefox is nice, but I ONLY use it for when I am writing some intense Javascript and need to use Firebug to help debug it. Otherwise I never have it open with all the programs I have open its stupid to even have it open with their memory issues.
