Another person logged into my firefox with their firefox account and all my password, bookmark, history got synced to their account.

When that person logged into their machine with their account, all my password is being synced to them. even after deleting while signedin, signedout and signedin again, all these get synced again. Could you please help on how to delete my data from that persons account.

Thanking You, Sincerely, Jinet

Resetting the sync password, or changing its e-mail, will remove all data from the servers.

This is a security feature. https://support.mozilla.org/en-US/kb/ive-lost-my-firefox-sync-account-information
