 Upon inspection on the blank element (right click on the blank login and select `Inspect Element`), the login box is an iframe of `https://passport.aliexpress.com`. From the Web Console (`Ctrl + Shift + K`), the following error message suggested it's caused by [X-Frame-Options](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options).

 From the Network inspection (`Ctrl + Shift + E`), `https://passport.aliexpress.com` has HTTP header `x-frame-options: SAMEORIGIN` (which I believe stems from the `XOriginPolicy` setting). This restricts the iframe to the same domain. This caused the iframe unable to load because it's different from the login page `https://login.aliexpress.com`.

 **Edit:** After pinpoint the issue to `XOriginPolicy`, I suspect AliExpress sends the referrer from `login` to `passport` for tracking purpose, and somehow `passport` could not be loaded if it does not receive any referrer. There are a few options to resolve this.

 That's how the whitelist works on the extension; you add the domain of the iframe not the page's domain. After you add it to the list, refresh the page and you should see the login.
