AliExpress login doesn't show up on Firefox. This is due to X-Frame-Options restriction. Here's how to whitelist it. AliExpress login doesn't show up on Firefox when there is a strict cross-origin policy (i.e. `network.http.referer.XOriginPolicy`). Here's how to whitelist it.

When you try to login to AliExpress on Firefox, the login box is just blank. ## Background

Firefox can restrict the referrer to the same origin only ([docs](https://wiki.mozilla.org/Security/Referrer)), by setting `network.http.referer.XOriginPolicy` value to 2 in `about:config`. Initially, I figured this would break many websites. But to my surprise, I have yet to encounter any issue; well, *except* for AliExpress.
When you try to login to AliExpress, the login box is just blank.

When I inspected the 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). In the new design, the loading wheel just keeps spinning.

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`. 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`. 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`.

[Ignore X-Frame-Options](https://addons.mozilla.org/en-US/firefox/addon/ignore-x-frame-options-header/) Firefox extension is a way to whitelist the domain from the restriction. By default, the extension whitelist all domains. This is highly discouraged because it nullifies the security benefits of x-frame-options (e.g. prevent a banking website from being iframe-d inside a phishing website). Instead, we can whitelist the login page only. **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.
## My Orders
To use the old login page, mouse-over on the **Account** link at the top right corner and click on **My Orders**. It should redirects to `https://login.aliexpress.com/...`

## Reset XOriginPolicy
1. Go to [about:config](about:config).
2. Search for `network.http.referer.XOriginPolicy`.
3. Right click and select `Reset`.

**Edit:** AliExpress has a new login which pop-up on the home page. However, it does not work even with the above workaround. ## Direct link
