terible, it does nothing when clicking in the chrome toolbar

works sooo good just one problem, when the user change the tab before the script is injected, it gets injected in another page, and not run in the page i wanted, can i do something to block the user to do that? or re-inject the script, even the tab in focus is another... just saying, thanks for the effort to make this awesome extension!
