Hi Alexmalex,

Firefox sync will store login information, but will not store your passwords. If you asked Firefox to save your passwords then those passwords would be stored on your machine. Which unfortunately means that if you did not back up your computer before re-installing Windows 10, those passwords are now lost.

If you logins are not syncing either, try checking the settings in your browser and make sure you have it set to sync logins. It should be under Settings > Firefox Account > Sync Settings.
