Page Monitor

This extension allows your browser to monitor changes to web pages for you. It can inform you whenever a particular page changes without you having to go and check every time. To use, simply go to a page you would like to monitor, click on the Page Monitor icon and select "Monitor This Page". You're done. Now whenever this page changes, the monitor icon will display a notification on its badge. Of course, you can repeat this for any number of pages. You can also change the check interval and badge color from the options page.
