What should I do to run 13 Firefox and Firefox 7 on a Mac?

13 Firefox works fine for every website I visit except Ancestry.com. Its support page says they don't support Mac users who use Firefox 7, so I would like to install it for use with this Web site only. I don't want to uninstall Firefox 13. What should I do to have both versions are available?

The simplest method for Windows users is to use portable Firefox. I don't know if there is something similar for Mac users.

The normal method is very important and just install the other version make sure he has his own profile. For now Firefox itself can be used to create new profiles using the Profile Manager.
