Hey. As you said your sync is working on other devices. I recommend, uninstalling Firefox and reinstalling. Be sure during un-installation you purge the folders related to firefox. Most importantly the ones in your %appdata% folders. As that is where user data is stored. The syncing issue may be caused by existing user data in the directory. Also after a windows 11 upgrade, there's a hidden windows.old folder in root C:\ where data that could not be copied during upgrade is left.
