If you have upgraded a version of Firefox to version 55 or newer, you won't be able to downgrade that version of the browser later on to an older version. While Mozilla never really supported downgrades of the browser before, it was usually no problem to downgrade a particular version of the Firefox browser. There are two main use cases where this happens: first, when a release version of Firefox causes issues, and when users use the same profile on different versions of the browser.

The first issue happens when Firefox users run into issues after an update of the Firefox browser. They may then install the older version of Firefox anew. Since Firefox picks up the default profile automatically, or another profile if you point it to it, it may be used automatically by the browser. This can lead to some issues regarding the profile, as new versions of the browser may introduce new features or change some.

In short: If you want to switch to ESR, it may be a good time to do so before the Firefox 55 release. You may alternatively create a backup of the Firefox profile before you upgrade to Firefox 55, and restore it after you install Firefox ESR on your system. 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. Once a profile has been used with Firefox 55 (or later), it should not be used with previous versions of Firefox. IndexedDB, the (DOM) Cache API, Service Workers, and the asm.js cache will all fail to operate, generating confusing errors and causing portions of Firefox and some websites to break.
