The new UI looks nice, but it often doesn't work properly in Firefox. Example: when creating a new login, toggling between "password" and "passphrase" does nothing! The selected tab will highlight, but the specific functionality for that password type doesn't render. Opening and closing from the toolbar icon seems to cause the extension to hang for a while. If I can manage to generate a new password - saving the login entry sometimes doesn't work and just hangs with the button disabled.
