I have a fairly old PC. My old Internet Explorer Browser got very slow, so I tried to download Firefox. Unfortunately IE would not let me download Firefox, so I had to use my old browser, namely AOL, which is still on my PC, but I rarely use. My new PC will come with Windows 7 on it, which I presume will also have IE. Will I be able to download Firefox with this browser, as it won't have AOL on it?
