Feature Request: access the list of passwords through a web based interface (also in other browsers)

Feature Request:
It would be useful to access the list of passwords through a web based interface (also in other browsers).
Supporting use case: if I lose my smartphone, I'm outside and I ask my friend to access the internet, how can I access my passwords?

Unlike some other browsers and password managers, we use end-to-end encryption of the login data so our server doesn't have access to the logins in order to show them on a webpage easily. There was a prototype by the Firefox Account/Sync team a few years ago though.

It could be done like protonmail do :
If i have well understand, the e2e encryption is based on a key derivated from the password.
So, the encrypted data can be accessible only with authentification to firefox-sync server,
then the firefox password derivation and the decrypting stuff can be done client-side, in browser.
At last, there is UI stuff to display the data.
