I have two questions -

Does anyone know where to find older versions of browsers (like IE 4.0 and Netscape 4.0) for testing sites - and how to install them on your computer so that you can use them, but they are not overwritten by the "latest version"? In lieu of that, any suggestions on how you test for older browsers (aside from understanding intellectually what is supported by what, or using the test feature in something like DW...)

Also - um, how do you disable javascript in your browser?
