As a personal project, I am helping a friend get onto the internet with an older pc running a 400MHz Celeron processor and about 512MB of RAM and running XP Pro SP2. With this condensed hardware profile in mind, which browser would work best with such an older system? While I would like to install the latest version of IE, I realize at the same token there might be the frustration of waiting for pages to load or even locking up due to insufficient system resources such as processor speed or even more importantly RAM. Perhaps there are other types and versions of browsers to better consider with older systems such as Mozilla Firefox, Opera, Google Chrome, etc., but, I am uncertain with regards to this idea.
At any rate, any tips or suggestions given here will be most appreciated.
