Hi again Cass, actually Firefox uses less system resources than IE7 so would help you use less memory. 512 MB is not that much memory anymore. I use a great little program called MaxMem to freemy memory (2gigabytes and still not enough for me!
) depending on what version of Windows,( I am assuming you to be a Windows user?)you are using it really gobbles the memory up.I am posting a link to Maxmem if you want to try it. It is a free program and a very small install. You have to start it again everytime you restart your PC it does not autostart
