Internet Usage extension for Google Chrome
Net Usage is a widget that lets you know how much of your internet usage quota you have left. It mainly supports Australian ISPs where often you are limited by how much you download each month. This extension works by automatically logging in to your ISP's usage page and extracting your monthly usage information. You will need to supply the username and password to your ISPs web portal. See the netusage website for full list of supported ISPs.
