Rated 3 out of 5 stars
Passwords is one thing, the vault is another, indeed. Hence, this add-on focuses on the latter and calls attention.
But how does this work in practice? How are passwords managed once kept in the pass-manager vault? Are they called in the same way as with Firefox Password Manager (double-click on the input field)? Do add-ons relying on Firefox Password Manager keep on working with pass-manager ('Secure Login' for instance)?
And what about the configuration options in about:config?
"There are some configuration options exposed via the about:config interface. The scope is extensions.passmanager.*."
Could those options be detailed? Moreover being accessible only within about:config?
Now, maybe is this add-on reserved for pros but then please mention it.
Neutral 3 rating since I haven't tested it for above mentioned reasons.
