Update since 16.5.2: All issues I previously had are fixed and it finally works flawless for me. Kudos to the team.

Old review pre-16.5 versions:
Would work like a charm, if there wasn't the big issue that it slows down page loads after a while significantly. Have to disable it completely in order to get page speed times back to normal.

I can't open the Keeper software because of the following note from Firefox-Mozilla:
Please update your Keeper app to the latest version from the App Store or from KeeperSecurity.com. If you are using a web browser, please reload the page or clear your browser cache.
Nothing I try seems to help make the Keeper P/W shortcut work.
HELP. Kermit, 10/29/2023

I loved Keeper - but ran into a very frustrating issue about a month after I started using it. Even with my being cranky, the support team didn't give up. After a bit of back and forth, they helped me resolve the issue. I appreciate the follow through. Good customer service makes all the difference!!

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

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