I do like Keeper and it works great for me most of the time. But there is a strange issue that embedded Tweets won't load on websites as long as the Keeper extension is activated in Firefox. I don't understand the reason for this but I could narrow it down to the Keeper extension.

I don't like having to create an account to use a simple extension so that's a no from me

Massive memory hog, triples resource usage in Firefox.

Just doesn't work with Yubikey. Can't even log in. Support response is to brush you off with the typical "delete everything and try again" rather than making any effort to diagnose and fix the problem.

Mehh! Unclear, complicated.

After latest update, there is issue with yubikey.

I love the extension and use Keeper for a very long time but lately the extension does not work properly. For example, I cannot even log in when the extension is active, I can reach the Web vault only after I disable the extension.

So far it has been working fine. But when come to github.dev or vscode web editor based website, this addon will somehow causing content not being loaded.

Extension Crashes browser to desktop when enabled.
No error messages given. Do not know why.
Does not allow function of the browser.
Does not allow login to Keeper Vault.
Crashes immediately.

Seems to work...mostly. Hesitates to work with some bank and credit card account logins, but it's not consistent...Almost like the Keeperfill extension gets blocked sometimes on certain sites. Especially noticeable right after updates to both Firefox and MacOS.
