Does your boss (or co-workers) check on what sites you visit while at work? Well, they probably have a need to do that, it is after all their dime so to speak – but you can close a non-work related tab by using the Simple Boss Key.

Once installed, all you have to do is quickly hit the F12 button to minimize the current browser window. One more useful tip to know if that is switches to focusing on the first tab, so even if something peeks at your operating system’s task bar – they won’t know what you were looking at before. So with that said, you should make sure tab number one is always looking at something work related, just in case.
