Web Content Monitor (WebEx) di Ayukawayen

Web Content Monitor is a tool to periodically track information on web pages.

To add a web content to monitor, right-click on a web page and click "Monitor Content" on menu, then select monitoring area.
The update interval and notification type could be set individually for each content. The add-on will fetch content values automatically in background, and the latest values of each tracked information will be shown in the pop-up panel.
