In Safari and Chrome, document.referrer reliably provides the referring URL, as expected.
   In Firefox, the value is often empty or incorrect, leading to inconsistent tracking results.

   Direct URL Open (Expected Behavior)
   In the first screenshot, we directly open the URL. As expected, document.referrer is empty because there is no referrer when the URL is opened directly.

   Clicking a Link (Unexpected Behavior)
   In the second screenshot, we click on a link from within our site. When we check document.referrer in the file, it still shows as empty, which is incorrect. The referrer should reflect the URL of the linking page.
