Tampermonkey is a browser extension that lets you run userscripts, which are small programs that can customize websites by adding features or modifying existing ones.
On the extensions bar of your browser, be sure that the Tampermonkey logo is pinned there, this will allow you to see when Tampermonkey has matched a site to modify by showing a red square with a number in it for each script active on the site.
Click the Tampermonkey logo and choose "Dashboard".
Find the tabs to the right inside the Dashboard, click the tab labeled "Utilities".
