Every time AdBlock is installed, the extension generates a random, unique code that identifies the installation, not the user (it's completely anonymous). Here's how to find it:
- Click the AdBlock icon in the browser toolbar and select Options or click the gear icon, depending on your version of AdBlock.
- Click Pay What You Want at the bottom of the page.
- The unique id is the final part of the text that appears in the browser's address bar.
