Chrome Incognito Killer

IMPORTANT YOU MUST ALLOW THIS EXTENSION IN INCOGNITO MODE FROM THE CHROME EXTENSIONS PAGE If you don't Incog killer won't even be able to see incognito tabs to close.

Incognito mode is for shopping, right?

Many people experience a sudden sleepiness shortly after they finish "shopping online", especially late at night after everyone else goes to bed. As everyone knows, a sleepy person makes mistakes like leaving tabs open to the websites they were "shopping" on.

If someone else uses the computer the next day, the "surprise gift" could be seen.

In comes Chrome incognito killer.
After a pre-defined time period (default of 15 minutes) of no activity on your computer, this extension will find any open incognito tabs and close them; hiding all of your "shopping activity".
Additionally, this extension will close any incognito tabs if it detects that your computer was recently woken up from hibernate mode or logged in from a lock screen.
