I-Firefox Isithangami Sokwesekwa

Hi everyone, I would like to know the way of saving passwords. Are they saved as plaintext ? Or ciphered and locally saved ? Is the Firefox solution as safe as Dashlane or other crypto-secure ways to save passwords ? Is there a technical documentation from Firefox about this topic ? Thanks in advance for your answers ;)

I've bought a new Win10 PC to (eventually) replace my old one.

I've signed up for a Mozilla account on the old PC, signed into it from the new PC and the favourites, history etc have come across ok onto the new one. The saved logons however haven't.

How can I get my saved logons to sync across from the old PC to the new one?

after updating firefox 89, it not longer auto fills logins or passwords, no saved logins shown and I cant manually enter a new login. I am signed into my account, but when I try to create a new login, it says to enter password, although I am already logged in. I have it setup to ask to save logins, the box appears but nothing is saved, I have auto fill checked
