(Optional) Install Firefox
Internet Explorer is very outdated and does not work with most pages. Therefore, we will be installing the latest release of Firefox that supports Windows 98.
You can of course install any other browser of your choice, but here i will show how to install Firefox.
Here is the original file from Mozilla. I have put this installer into an ISO file, so you can install it without problems.
