My LastPass extension appears as a black box with an elipse. It is red when it is active. I have logged in to LastPass, and when I go to the extensions icon and select "Open Extension" nothing happens. It's not filling in any of my login information.

Try uninstalling LastPass, restart the browser then re-install.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.
