You have to do a custom install and install to a different directory otherwise the beta will replace your existing FF installation.
It's also best to create a new profile for the beta install.
I installed the Beta in a separate folder but used the original profile and had the same extensions and bookmarks.
It worked OK but didn't notice much different. I uninstalled it today when the new FF 56 was released.
