CMScrape-Extension is a firefox add-on made to easily create list of links from CardMarket. It was specially developped to keep track of all your collection's price using CMScrape.
CMScrape-Extension is available directly on Firefox, or you can install it as a temporary add-on on your broswer of choice.
Open the about:debugging page, click the This Firefox option, click the Load Temporary Add-on button, then select any file in your extension's directory.
The extension now installs, and remains installed until you restart Firefox. Source : developer.mozilla.org
