makes firefox unusable, slows down to a crawl

have to keep the extension disabled or just use the website

Slows down Firefox so much that I had to disable it

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.

Autofill does not work on many websites.

Nice app

This extension progressively slows down Firefox as it reaches extremely high CPU consumption.
I need to keep it disabled unlesss I need to use it.

Strong password protection. Not easiest to use, however, it is very useful and protective.

This extension is lagging and slowing down firefox so much, that I genuinely have to disable it when I don't need to use it because googling something or opening a new page adds an extra one or two seconds of loading in order for the website to load instead of them loading in under a second. It is infuriating. Even with all of the prompts and recognition of password fields disabled, the extension still lags webpages an extreme amount.

Current version seems to slow down Firefox

Love it!

Super convenient, on all my devices. Easy to add to and revise, clear interface.

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.

Always responsive to user queries.
Exceptional security by requesting authentication first ( very few sites work this way ), especially if this involves a hardware security key ...
Canadians should log in to CA server ... not explicit in info though and keep the site in their bookmarks

Great Addon. The lastest version (17.1.1.) doesn't stay logged in when I close firefox. Version 17.01 worked without problem.

Pretty easy to work with. The code for the 2FA is quick so I like that about it. Tells me when to change my passwords due to compromised logins and such. I enjoy it better than lastpass or whatever.

Plugin hangs the entire browser, eating all available RAM. This can be anywhere from 10 seconds to 5 minutes. No key combination for auto-fill. Terrible interface. Only use it because I have to.
