I see where Firefox Quantum Beta can be downloaded. I currently use Firefox. I would like to try Quantum, but do not want to risk losing all of my current functions in Firefox. If I choose to execute the Quantum installer, will it write over the top of my current Firefox, or give me a new browser to use?
