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

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.

This addon is incredibly slow. Additionally, login credentials cannot be restricted to specific URL paths. With some servers, the correct credential must be reselected each time you log in. Together with the extremely slow selection popup, a very annoying experience.

Reliable app with excellent cust service!

" Keeper " does exactly what it supposed to do. It is simple to use and offers an extremely safe way of handling all the passwords etc. that we have to deal with in this electronic age.

Doesn't make sense that I have to use the Master Password each time I log in to PC. On the phone, things auto fill as they should. On PC I have to type the master each time. Which means I must look at the app on my phone and type in a long password. Unfortunately my phone was damaged and I can't log in to Google on a temp phone due to inability to access my Keeper on PC.

No longer works with Firefox developer Edition. Still works fine with regular Firefox.
