In August 2007, a security vulnerability allowed a hacker to expose Facebook's actual PHP source code. The retrieved files included index.php (the homepage) and search.php (the search page), revealing raw business logic that was never meant for public consumption. This incident served as a wake-up call for the industry about the importance of securing server-side code.
| Area | Purpose | |------|---------| | | Hidden inputs ( <input type="hidden" name="fb_dtsg" value="..."> ) to prevent request forgery. | | Preloaded data | JSON inside <script type="application/json"> or inline JS objects — could leak test flags or user settings. | | Meta tags | og:title , al:android:url — deep linking behavior. | | Module names | __d("CometHomeRoute.react"... — reveals internal component names. | | API endpoints | Strings like \/api\/graphql\/ or \/ajax\/browser\/ show internal APIs. | | CSP headers | Not in source but in HTTP response — view via browser dev tools > Network tab. |
Here are some things you might notice:
Your fancy React app might look cleaner, but Facebook’s messy source code loads faster on a Nokia.
: Be wary of tutorials that ask you to paste code into the "Console" (F12) while viewing the source. This is a common hacking technique called Self-Cross-Site Scripting (Self-XSS), which can give attackers control over your account. How to Use the View-Source Command If you want to try it yourself: Open your browser (Chrome or Firefox work best). In the address bar, type: view-source:https://facebook.com Press Enter .

Viewing the source code of the Facebook mobile homepage is a common technique used by developers or researchers to find specific account details, such as a , or to analyze the site's underlying structure. How to View the Source Code To see the code for https://facebook.com :
Notice URLs like https://static.xx.fbcdn.net/ – these point to Facebook's global CDN, ensuring static assets are delivered from servers closest to users.
Understanding and utilizing view-source: can be immensely valuable for several professional activities: Elias blinked
For dynamic single-page applications (SPAs), the view-source: view becomes increasingly different from the live DOM. The DOM seen in browser developer tools reflects the page after all JavaScript has executed, including modifications, event listeners, and dynamically injected elements. For highly dynamic sites like Facebook, the initial source may bear little resemblance to the interactive experience users ultimately see. Developers should use panel (F12 → Elements tab) for live DOM inspection and the Network tab to examine raw server responses.
While using view-source:https M.facebook.com Home.php might seem harmless, there are some implications and concerns to consider:
