You don't need this. Firefox's design here is very poor, but you can save to PDF by first going File -> Print, and then clicking on a button that simply says PDF, and then "Save to PDF". Absolutely idiotic design by Firefox. Also, this extension does not work properly as it sends a URL to some server, which means anything you were logged into is likely not going to work, AND it's probably a violation of your privacy.
