The only reason I'm only giving 4 stars is because it tends to slow down/interfere with Mozilla. I frequently have to disable it for a while.
But I LOVE LOVE LOVE having my passwords handy and secure.

I have been using Keeper for over 10 years now! I have never experienced any issues where I wasn't satisfied! However, I can't compare Keeper with any other password security software because Keeper is my first! But I wouldn't change to any other password security software even if they paid me to change! I'd just take the money and run! Keeper is my Keeper for life!

Simple et pratique.

Based on my experience: disable-for-domain feature is must-have for this extension. In the other way you'll have annoying popups

works as advertised

I have tried most of the other password managers, and I like Keeper the best for Windows (Firefox) and iPad (Safari).

However, there is one glaring issue: if you are using 2FA, Keeper requires the 2FA code for every sign-on to Keeper. The extension also will not remember the user's email address. This may have something to do with my settings; I'm using the tracking protection and also clearing cache/cookies on exit from Firefox. I would still expect Keeper to handle this without requiring the 2FA code each time. The Chrome version of this extension handles 2FA just fine, and I'm running incognito with Chrome.

Seems not to know my passwords yet

Excellent tool I've used it with both Chrome and Firefox, one feature I would like to see is an ignore page/site function so it does not interfere with pages or websites i don't it on.

one Bug I only see in Firefox is on a few work web services I use there are so many fields that keeper freezing and locking up the page and I either have to use another browser or disable the keeper extension to make it usable.

In my business I am constantly logging into different sites, both for work and private purposes. Having this extension active allows me to get my work done faster, not having to worry about my login and password for each site. I probably don't use it to anywhere near it's full potential, but what I do use it for is great!!!
