There were signs of life to indicate that it was running - but it was unusable. I rebooted - no good. I uninstalled and reinstalled - no good. I finally downloaded and installed 56 from Mozilla then quickly shut down WiFi and disabled auto-updates before it could upgrade to Quantum again.

Mozilla was working on this upgrade version for a long time, which has been introduced to the final users. According to Mozilla, the Firefox Quantum version will run twice faster and will use 30% less memory than Google Chrome.

In addition to speed testing, Firefox’s “just right” multi-process architecture results in Firefox Quantum consuming roughly 30% less RAM than Chrome.
To compare memory usage, the atsy project was used to load 30 pages, each in its own tab, with 10 seconds in between loads and 60 seconds of settle time at the end. Then memory usage was measured for the various processes that each browser spawns during that time.
The new Firefox. Fast for good.
With 2x the speed, built-in privacy protection and Mozilla behind it, the new Firefox is the better way to browse. Get the new Firefox.
