Chrome Extension for Facebook login session data

Need an EXPERT at Google Chrome Extension Development to check browser extensions' source code & duplicate the functionality. GOAL: Create an extension that allows the user to grant permission to share their [login to view URL] login session data. EXAMPLES: RentaFB (Updated January 21, 2019): [login to view URL] FB Club (Updated February 6, 2019): [login to view URL] FB Dollars (Updated September 27, 2018): [login to view URL] FB Cash (Updated February 21, 2018): [login to view URL] EXPLANATION: " We have performed a research and to answer your question “Explain to me how the extension accesses the user's FB account?” we can say: The extension receives user’s web session and fingerprint (locale data) - then it erases user’s browser session to make logout impossible while the extension uses this session. Then the extension calls API and web socket server to get info on current status, amount of money received and sent to user, and also implements a Javascript code. " REQUIREMENTS: - check my example extensions' source code & fully understand the code - explain to me how the web session and fingerprint data are grabbed - implement similar functionality on client and server side After you complete the new extension, there is also opportunity for further work maintaining the extension or adding new features. Are you 100% sure you can understand the Chrome extension source code & help me implement similar code on client and server side?
