I have been using this for many years. Very reliable, easy to use, constantly improved and I have recommended to a number of friends.

The UI works well, it enters passwords nicely, no issues with functionality.

However it greatly slows down Firefox over time. At first startup it's barely noticeable - but if Firefox has been running for a few hours it can be excruciatingly slow, especially on pages that have been kept open but have had a lot of content updates.

This extension made Firefox really really slow. It looks like that they fixed the performance problems with 16.5.3. Thanks!

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.

I just bought the family version and created an account on FireFox but it does not look good.
First I was given an option to import my old password, but after the first dialog it froze and couldn't get back to how to import my old passwords from lastpass.
Next, I tried to install the extension from Keeper's page, but that link doesn't work, However after searching for it from within firefox add-ons page I found it, installed it but it's not clear how to use.
It's my first day, chose b/c of some reviews online, but I am getting the impression that it's very buggy, crossing fingers.

Can't make it work with Firefox. There's no point in having it. I'm going to ask for a refund and go back to Lastpass.

I really like Keeper, it's one of the better full service password management, auditing, and automation solutions. And the Chrome extension is really good. But the Firefox extension is buggy. It looks the same, but doesn't always work and it's EXTREMELY slow. You can see Firefox use up a ton of CPU when just switching tabs or reloading a page, then disable Keeper and it's lightning fast again. I'm not sure what is going on, but they really need to fix this bad. This is a show stopper.

** EDIT **

It's been months and still no fix. This is unacceptable for a service MSPs are paying for.

Fill button barely works and is intermittent.
Latest update has killed the sign in, it shows sign in success but never signs the add-in in.

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

Нет истории генератора паролей. так что помошником при смене пароля лучше не пользоваться.

Разлогин при подключении впн.

If you are looking for managed password manager with unique extras and multiplatform, look no further! Works on LInux, and iOS as well too.

Amazing app! Super easy to use and reliable!

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

Some times it works at times it does not. With the hover link on I cannot input my saved password to a webpage. Please update this addon asap.
