1800800 - Able to access stored password from browser and decrypt them.

Status: RESOLVED INVALID

(Toolkit :: Password Manager, task)

Description

It was discovered when I was trying to figure out how the security of the browser worked.

You have to remove the saved files in the browser (C:\Users\XXX\AppData\Local\Mozilla\Firefox\Profiles\XXXXrelease) onto a usb. You can then have an unrelated broswer on a completly different computer emulate itself as the first one and decrypt the stored passwords.

This is well-known property of the current implementation so I don't think it needs to be hidden as a sec bug. Right now, if you don't want this to be possible, set a primary password (in which case you'd need the primary password in order to decrypt the passwords, on both machines). In the future we might look at using OS-provided crypto stores to tie the passwords to the local user account, but that would need some UX work for when users e.g. migrate machines.

Thanks for the report, but this is how browser is supposed to work. You can use Primary Password to add an extra layer of protection.
