chill-out

What it does

After 6 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 https://giphy.com/explore/cat.

The delay of 6 seconds is to make the extension’s behavior obvious, but such a short period is not recommended in practical applications. Note that in Chrome, alarms do not fire in under 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.

What it shows

How to:

• use various tabs functions.
• show and hide a page action.
• set alarms and handle alarms going off.
