Yes it is possible, don't use the same profile, and you will have to use "-no-remote" on the one that is not your default browser and/or not your default profile.

It's a lot easier to use a Firefox Portable version for your other installation, it won't interfere with the 1st version you have installed and you won't have to deal with "Profiles".
