Firefox Sync failure

Hi Yesterday I replaced my computer. I'm trying to sync my account data, but unfortunately, nothing is syncing. I have all the data selected for syncing (bookmarks, history, etc.), and the logs in about:sync-log are empty. It looks like the data from your server has been cleared. Firefox is freshly installed. Please help.

Sorry, but if your data is not on another device there is nothing we can do. Where is the old computer?

Sync info... FYI... Firefox Sync IS NOT A DATA BACKUP SERVICE https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer https://support.mozilla.org/en-US/kb/how-do-i-choose-what-information-sync-firefox https://www.mozilla.org/en-US/firefox/features/sync/ https://hacks.mozilla.org/2018/11/firefox-sync-privacy/ Sync is not a backup tool but it is a good sync/transfer/move tool https://support.mozilla.org/en-US/forums/contributors/707681
