This add-on is incredibly handy and innovative but it causes Firefox to become totally unresponsive on some sites that it doesn't even provide functionality for, at least not that I can tell.

If the performance issues cannot be solved I'd appreciate a button I could add to my toolbar to quickly blacklist a site for the add-on.
