User Reviews

Users find the Password Manager practical and mostly reliable, especially appreciating its capability to detect leaked passwords. However, repeated prompts for the master password on startup and the misidentification of distinct login sources as duplicates are notable drawbacks affecting user experience.

Pros

Effectively identifies leaked passwords, enhancing security.
Generally reliable and functions as intended.
Practical for managing passwords across different sites and sources.

Cons

Recognizes multiple login sources for the same account as duplicates, causing frustration.
Requires frequent re-entry of the master password upon system restart.
Sometimes demands repeated authorization code entries for functionality.

It treats what it thinks is duplicates (actually what it is, it's another login source through for example i have account on my launcher for blizzard copied. And another on a official blizzard site. It treats that as duplicates which is very disapointing. But other then that it works as supposed to, And recommend you to switch regularly your password.) Also tells you if your password has been leaked which is very very good

Is Password Manager Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Password Manager requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Password Manager is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
