I want to test the new Quantum 64 bit without removing my 56.0.2 (64-bit) on a Windows 7 PC. My concern is that I will lose my extensive cache, bookmarks, useful plug-ins and add-ons, etc., if I install the new Quantum and it overwrites everything.

Yes, you can! Download and install them in separate directories. Then, launch each one individually with the -p flag to set up different profiles for each version (or at least one for testing). Then, after you have two separate profiles, create an icon for each on your desktop. Right click on the icon and select properties. In the 'target' field, add the following flags. c:\Programs\Firefox 56\firefox.exe -p Profile1 -no-remote c:\Programs\Firefox 57\firefox.exe -p Profile2
