You can't use two different versions, the newest will always dominate. 
If you do need 2 separate versions then you will require either a 
virtual pc setup, or a usb key (I prefer this) or other media. This 
happens with most applications on windows. I can do this on Linux buts 
its a different can of worms.

Portable Firefox http://portablefirefox.mozdev.org/ can help you do this.
