Firefox synchronization worked on all my devices, my login credentials and passwords being perfectly synchronized. The problem started when I was offered to install the Lockwise application on Android. When connections were available in the Firefox application for Android, they did not synchronize with the Lockwise application. The synchronization performed in infinite loop and synchronized nothing. Reinstall or restart did not help. From this moment, Firefox for Android has proposed to enter the passwords of the Lockwise application, but since no password has been synchronized, there was none to fill . I've decided to uninstall the Lockwise application and return to Google's auto-entry service for global management of my Android passwords. But in the Firefox application for Android (which I use most often), I still like to use Firefox Sync's built-in AutoFill feature, as I'd usually do it before installing the Lockwise application. Firefox for Android no longer offers to enter a password. When I look in Tools> Connections, all my passwords are there, perfectly synchronized.
After some research, I checked if the following items concerning: configuration Booleans were enabled: and yes, they were.
