This is a representation of the code behind the Facebook mobile login screen:

The "View Source" feature on mobile Facebook presents both benefits and risks. While it can be a useful tool for developers and power users, it also raises security concerns. Our study highlights the need for designers and developers to consider the security implications of "View Source" features and to educate users about potential risks. We recommend that Facebook and other mobile web developers take steps to mitigate these risks, such as providing clear warnings and educational resources for users.

If you are on a mobile browser, you usually need to prefix the URL with view-source: , for example: view-source:https://m.facebook.com .
