"In short: If you want to switch to ESR, it may be a good time to do so

What is ESR?


Mozilla notes that the organization changed the "on-disk format of
persistent storage in profiles" in Firefox 55, and that this change is
the reason why you cannot downgrade to an earlier version of Firefox
after you used the profile on Firefox 55 or newer."

Uninstall the current version and install an earlier version.
