chill-out

What it does

After N seconds of inactivity (defined as the user not having navigated or switched away from the active tab) display a page action for that tab.

When the user clicks the page action, navigate to http://chilloutandwatchsomecatgifs.com/.

"N" is set to 6 seconds in this example. Such a short period is chosen to make the extension's behavior more obvious, but this is not recommended in real life. Note that in Chrome, alarms cannot be set for less than a minute. In Chrome:

• if you install this extension "unpacked", you'll see a warning in the console, but the alarm will still go off after 6 seconds
• if you package the extension and install it, then the alarm will go off after a minute.
