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.

Used to work great, however more recently the popup box next to password fields immediately vanishes/moves off-screen as soon as it appears. Errors in the console mention issues with font downloads ("kern: Unsupported table version: 1", "Table discarded", etc). Switching back and forth between tabs makes it appear on-screen again, but that's far from obvious...

Keeper is awesome I think I missed a couple of updates but this latest update has a ton of features that have really improved the app. the whats new thing is pretty cool to for giving a summary of the new stuff. like the feature they added to have multiple accounts too - lovin it! I also like that you guys added the ability to show what my master password is when I am logging in because I sometimes make a typo and it's nice to be able to unmask it so i can see what i typed wrong to fix it and login. I had to accept some new permissions with this latest update I guess this cause of the disable other password manager thing.

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.
