If I install Firefox Quantum, does it install over my present Firefox browser (57.0 (64 bit), or is it separate from that browser?

Firefox Quantum is Firefox 57.0, they are one and the same. Quantum is just the code-name for the next few series of Firefox releases. If this answered your question, mark as solution!
