User Reviews

User reviews praise Keeper for strong security and solid Firefox integration, including reliable autofill for passwords and responsive support. However, autofill is inconsistent across many sites, with freezes, incorrect entries, and popups, and there is a noticeable performance hit—high CPU usage and slow page loading—causing some users to disable the extension. Overall, Keeper is valued for security and usability on Firefox, but autofill reliability and performance impact are the main concerns.

Pros

Strong security and protective features (including support for passkeys).
Generally reliable password autofill and login experience on Firefox.
Responsive, helpful support when issues arise.
Good Firefox integration with fast, convenient autofill for passwords.

Cons

Autofill is inconsistent across many sites: not filling correctly, prompts freezing, popups, and no blacklist to suppress on troublesome sites.
Significant performance impact: high CPU usage and slow page loading, often forcing users to disable or remove the extension.

Slows down the browser to the point that it takes 5-10 minutes for the application to open. Trying to install the extension bricked my Firefox installation around five times before I got it to work. These are likely related to the fact that I have a few hundred open tabs, but it's nevertheless unacceptable. I would use any other password manager (Proton Pass, Bitwarden, ...) if I could.

Is Keeper® Password Manager & Digital Vault 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.

Keeper® Password Manager & Digital Vault requires a lot of sensitive permissions. Exercise caution before installing.

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.
