How can I be 100% sure that my passwords are not stored somewhere?
I've been deleting my saved passwords in Firefox, after migrating to a standalone password manager. It's been anything but easy (deletions are not synced, and bulk deletion process is inconvenient to say the least).
What worries me is that my "deleted" passwords kept coming back as soon as I enabled Sync, until I realised I had duplicate devices in my Mozilla account control panel. I still have, though, some other connected services (Add-ons, Mozilla Support, Mozilla Monitor...).
Is what I've done enough to ensure they're gone? Where exactly are synced passwords stored, and how can I be sure that they aren't lying around in a Mozilla server, awaiting a future data breach? I don't have the time and energy to change 200+ passwords.

Hi
Do you have Firefox installed on another device?
Currently, only in the three devices listed in control panel.
If you take all the devices offline, remove the passwords from them, turn one online and then remove any passwords that may appear in Firefox, they should stay gone on the other devices.
