This extension has been broken for me for about a year. I believe it has something to do with the fact that I use a security key to log in, because other users seem to be able to sign in with it. When I try to sign in after entering my password the loader never stops spinning and this error is printed in the console: "Uncaught (in promise) DOMException: A parameter or an operation is not supported by the underlying object".

Please stop opening a new tab telling me how to pin the keeper addon to my toolbar: I don't want to pin it. I keep most addons unpinned. This is obnoxious behavior and makes me resent having to use keeper.

Recently started using Keeper in work, which seems to work okay in itself. This extension, however, doesn't. It basically hangs Firefox and makes it consume memory until there is no more to consume – and I have plenty. Must disable it to not kill my whole system due to memory shortage. Haven't been able to log in yet. Version 16.7.6 on Firefox 123.0 (64-bit), macOS 12.7.2 (x86).

I don't like having to create an account to use a simple extension so that's a no from me

Massive memory hog, triples resource usage in Firefox.

Just doesn't work with Yubikey. Can't even log in. Support response is to brush you off with the typical "delete everything and try again" rather than making any effort to diagnose and fix the problem.

After latest update, there is issue with yubikey.

Extension Crashes browser to desktop when enabled.
No error messages given. Do not know why.
Does not allow function of the browser.
Does not allow login to Keeper Vault.
Crashes immediately.

Doesn't work after latest release. At first it would log in but refuse to populate anything and now I can't even log in.

SSO login does not work anymore. The extension is unusable.

Latest update refuses to log me in. Completely useless now.

Had to roll back to 16.5.4. Thank goodness Firefox keeps a version history! (Thanks Mozilla).

They really do not care about Firefox users. That's been obvious before and it's even more obvious now. Nobody tested this.

Latest version (16.6.0) not filling in password any more at all.

Had to downgrade due to 16.6.0 being broken and non-functional. Suggest Keeper Security Inc. actually apply quality control before issuing faulty updates. Also, a lot doesn't work on a LOT of sites.

Version 16.6.0 doesn't recognize any site stored in my vault. I had to downgraded to version 16.5.4 and disable auto update.

Last version 16.6.0 does not work at all. I have to move back on 16.5.4

The most recent update has made it mostly dysfunctional. Before this it wasn't perfect, but it did what it needed to do and was a little bit better than most other password managers. Now all features related to autofill does not work. How such a massive flaw made its way into a release I have no idea

How this password manager has got so big is beyond me, the functionality is rubbish. The auto fill doesn't work (ever). Sometimes the extension fails to even load. It never recognizes when you change your password so you have to change everything manually and generally it's a lot more difficult to use than other password managers out there.

Update: After an update the browser extension doesn't even load. Changing to 2 star from 1 star

It keeps telling me that it's not up to date even though it is. It will not run.

Breaks very often with browser updates.

In terms of encryption, reportedly among the best. In terms of user experience: personally, very bad. It does not "see" where it must fill information. Most of the times, automation does not work: you need to open the vault and copy-paste bit by bit. And now, the extension no longer works because the update does not work. I won't renew my subscription, that's for sure...
