Possibility to restore profile from Cloud

Hi, for an unknow reason all my passwd list was rested on my laptop. All profile present on my local drive didn’t contain any login/passwd, so I would like to know if there is a backup down of our profile on the FireFox CLoud, to permit to restore it from 3 days ?
Tks for your feedback.
If I loose all my passwd, it will take weeks/months to recover all …
Tks for your support and answer
