I have a remote access account at work, that works with Ver. 4 but does not support V.5. Can I download and old version (4) and have both on the home PC at the same time?

It is possible, I use multiple versions, however Firefox official policy is that you use firefox3.6 or 5 ; not firefox 4 which is not secure and not supported.

The easiest solution may be to use firefox portable http://portableapps.com/apps/internet/firefox_portable/localization#legacy36 although firefox 3.6 will itself not be supported for much longer.
