Get your monthly Videotron Internet usage
Warning 19/08/2014: I'm no longer a Videotron client and my account has been disabled. From now on, I'm unable to check if this extension is still working.
This extension display in the toolbar the monthly usage for the current billing period. A tooltip with the billing period dates is displayed on mouse over. The data are automatically updated every hour. A click on the icon force a refresh. But be careful, too many request seems to trigger some "protection" and the returned value become 0 for a certain period of time (and anyway Videotron update the data only a few times a day).
You must set your user id (VLxxxxxx) in the config. Then save, and click on the icon in the toolbar to force a refresh.
This extension is very basic and any change in the Videotron web page template can break it.
In that case, you can contact me and wait for a fix, or download the code from GitHub and try to fix it by yourself.
