Discovering IDs for Firefox Add-Ons

Step 1 – Finding add-on IDs requires a little bit of work. To discover them, you need to click on "Add-ons" in Firefox on an example computer, as shown in Figure 18.

Step 2 – Then, click one of the four categories below:

  • Extensions
  • Appearance
  • Plugins
  • Services

Step 3 – Then, press F12 for developer tools. In the lowest row, paste the snippet of code supplied below, as shown in Figure 19.

NOTE: You may get a warning saying you cannot paste until you say it's okay. To permit pasting, type allow pasting," as shown in Figure 20.

Step 4 – You can use this snippet to discover IDs for extensions, appearance, plugins, and services:

var addonElements = window.document.getElementsByClassName("addon");
for (var i = 0; i < addonElements.length; ++i) {
var addonElement = addonElements[i];
console.log(addonElement.attributes["name"].value + " = " + addonElement.value);
}

Step 5 – Paste the snippet into the lowest place on the page, as shown in Figure 21.

The result you will get (which is to the right of the equal sign within quotes) will be the name of the GUID or friendly name, as shown in Figure 22 and Figure 23.
