Hi, I need to create an extension for firefox 45 that would allow me to intercept a link click so that I can launch a custom download manager. The only example I can find puts the javascript into the page. ([https://github.com/mdn/webextensions-examples/tree/master/notify-link-clicks-i18n](https://github.com/mdn/webextensions-examples/tree/master/notify-link-clicks-i18n))

Can someone help me figure out how to do this?
