Poor user experience. I use this extension for work, where I have a single sign on provider, so I use 1password around once or twice per week. This means, every time I open 1password, my SAML SSO session is expired and 1password fires a new tab immediately to sync the changed passwords, completely disrupting my work. Editing an entry within the extension is also a no-go, it opens a pop up (where I have to log in again). I would expect to do more stuff within the extension and less stuff in a new tab, if I want a new tab I wouldn't use the extension. Copying the password is harder than autofilling (I would expect a keyword shortcut), but autofill sometimes auto submits, which makes it a very poor experience, especially when the form has other fields that 1password is not capable of filling. I only use this for work purposes.
