I always try logging in and trying to sync my browser after reinstalling Windows but Sync is not Syncing on all my devices I am sure that everything is correct because I have been using Firefox since the first release But I think there's a sync problem, maybe my data was removed from the server Is there any solution? thank you

Please give some details. How many units are in the sync? Are some fully syncing but others do not? Is it partial sync on some units?

You can open about:sync-log via the location bar to see if there is a recent log available. You can upload a recent log if the log is too big to put in a reply.
