That PPA is used to build beta candidates of firefox, in preparation for actual releases. Unless you're willing to test unstable (and possibly uninstallable) packages and file bug reports for issues you encounter, you shouldn't be using it. If you do want to test and report issues, you're very welcome to do so, but beware that this may break your firefox installation in unintended ways, so don't do that on a production system.
