From https://bugzilla.mozilla.org/show_bug.cgi?id=1000323#c18 : "STR: 1) Go to Settings > Firefox Accounts 2) Log in 3) Go back, enter Find My Device, notice how it properly shows the Enable/Disable switch 4) Go back to Firefox Accounts 5) Log out 6) Go back to Find My Device, notice how it still shows the Enable/Disable switch In step 6, we should see the login button in FMD, which is displayed when onlogout fires. Also, FMD logs a message to the console whenever onlogin/onlogout fires, and that message is not logged for logout -- which further indicates that onlogout is not being fired. Note, however, that if you close the Settings app, reopen it and go to Find My Device, that will cause a new call to navigator.mozId.request() to be made, which successfully fires onlogout then."

Hi Jed: a simple patch to add a missing event volley. Thanks!
