After some time the autofill stops working and it starts freezing the browser briefly every time a page loads. Had the same thing happen on regular Firefox and on Waterfox.
On top of that, there's no way to blacklist some sites from autofill, which results in annoying auotfill popups or the KeeperFill icon covering some smaller input fields completely.

It looks like the latest version 17.1.1 slows down the browser very much.

With version 1.7.1.1 every time I close the browser I lose the login. This misses the point of an extension, which is to simplify life, so it complicates it.

The plugin sometimes slow down the whole browser to the point where Firefox asks you if you want to stop the addon.

It also tries to autofill the search bar on youtube

Password managers walk a fine line between helping you login quickly and being the most annoying thing possible.

This one is the latter. It constantly autofills when I don't want it to, does'nt autofill when I want it to.

Copying and pasting passwords from the vault is tedious.

Generally quite ok, but this plugin feels quite buggy at times. For example, it is not possible to open the clipboard manager when password inputs are focused. The huge icon in input fields is also quite annoying.

When it works, it works well. However, it has two major problems:

1. Frequently just stops auto-filling entirely (only on Firefox, I have not noticed this problem in Chrome). No idea why. The extension is active and I am logged in. Sometimes restarting Firefox fixes it, sometimes not. If you contact support, they say "reinstall the extension, reset your browser to factory settings, etc." Sorry but those are not acceptable solutions.

2. The sync between devices seems either broken or much slower than it should be. If I add a password on my phone and then check in this browser extension, the new password is nowhere to be found BUT if I log out and log back in, it appears. Infuriating.

The extension worked great, but now it loops after the attempt to login with SSO and does redirect, causing an infinite load

Slows down web pages, especially Github. Auto-submit still doesn't seem to actually do anything.

It stopped working. It sucks...

Slow and nearly useless on Firefox/Ubuntu. It takes forever to load, it it loads at all. It's not great on my Mac either.

Technically can work, but frequently either bugs out (clicking the button doesn't open a window at all), and really slows the browser down. Had issues where tabs or network requests would hang for 10-30s at a time, and couldn't figure out where the slowdown was coming from. Finally profiled Firefox enough to see lots of 'jank' in the WebExtensions process, so I just tried disabling Keeper and boom, problems resolved.

Keeper works very well, but this plugin unfortunately is buggy. Often it's unable to fill-in the proper inputs, and it's laggy too

No bio-metric support for the browser extension. YEARS behind 1Password, Bitwarden, Enpass, etc.

This addon makes other addons which provide another tab view on sidebar, for examples Tree Style Tab, Sidebery, Tree Tabs etc. very SLOW. When I disabled it (without uninstall), the other addons works much faster. I assume that the addon handle some tab related event and do some heavy task on it. I hope they improve this behavior. If it won't hinder other addons, it would be so useful for me. Thank you.

Ist OK jedoch muss man alle paar Minuten das Passwort wieder eingeben. Das stress mega. Solang ich am Rechner bin, soll der eingelogt bleiben. Über die Desktop App kann man nicht direkt zugreifen und muss sich auch wieder einlogen.

A recent update introduced a nagging screen when you're not logged in ("Please login by clicking the icon in the toolbar"). I don't want to login every time, I only want to login when I need to use it!

The UI is very primitive. It doesn't even ask which folder it should save the password in!

Consistent with the rest of the Keeper experience. "It works, but..." is the best way I can describe it.

User experience is pretty terrible. It works with little icons in the text fields, but the pop-up that tells you to log in comes from the extension icon. Click the extension icon, however, and you're greeted by... settings. No logins there. Why they didn't just simplify everyone's life by putting everything into the icon is beyond me.

But logging in TO KEEPER happens in the icon. So logging into a site often requires you to juggle between the icon in the top right and the icons on the fields. That's assuming the icons work though, because leaving your browser unattended for a long time could cause it all to stop working and require a browser restart.

They recently changed the interface. Now you've got to click a couple more times, because they put the email address, password and 2FA on different pages. Terrible idea.

Logging into the extension and the app are entirely different processes. You need to log into both separately. The app has Windows Hello, but the extension doesn't.

The extension settings' interface is just plain weird, with green-on-blue dots indicating things that are turned on (accessibility anyone?), yet those "toggles" don't really do anything. They bring you to another page where you can check the setting. Why?

Also the desktop app by default adds global keyboard shortcuts that could very well break functionality in other programs.

And with today's update (early May 2021), they broke the thing completely. Can't type my password beyond a few characters, and even if I paste my password in, can't log in. Normally I'm pretty tolerant of bugs, but from a product that feels unpolished all around, it's harder to forgive.

Having tried LastPass (not great but still better than Keeper), 1Password (great on Mac at least; didn't try other platforms) and Bitwarden (great on most platforms; slight issues on Android), Keeper is the worst password manager yet. It just doesn't feel polished. I'm regretful that my employer picked this one.

It was working perfectly but in last last few days the Keeper session is dropped after few minutes forcing me to log in every 15 or 20 minutes.
I have the same problem in Firefox and Chrome, both on the latest update

The addon works, but it steel keep high CPU usage.
When i check on "about:performance", Keeper Addons has most energy impact on Firefox
