2 of the most important and commonly used programs, for me, are Roboform and Google. After many hours and much research, they do not work in FF 5.0. So, I simply need to go back 1 version.

if an extension worked in Firefox 4.0, it should be working in Firefox 5.0 as well.

You can force 5.0 "compatibility" with the "Compatibility Reporter" extension, or with extensions.checkCompatibility using about:addons.

For those that really need an earlier version of Firefox releases or for Firefox 3.

When reinstalling Firefox from a download, Firefox must be down once the installation starts. When the installation finishes, don't let the install start firefox for you. Instead end the install and start Firefox in your normal manner, thus preventing creating a new profile which does not have your bookmarks cookies, etc (but your old profile would still be around and would).
