We are launching a Browser from our Python back-end code. This opens a 3rd party's URL , where the user needs to submit a form. After submitting the form , the browser instance should close automatically. We tried from Python's side but it is not possible to manage the state from back-end. Can we write some Javascript wrapper at front end to handle this?

You can't.

Javascript can't close the browser from inside or it will be tricky

Unfortunatly, if you don't have access to the 3rd party js code or an API informing you that request has been submitted, you can't even know when the user has submitted the request.

Switching on window.close(), if your application is opening only one window, you can use the:

window.close()

method. This method will close the current window. So, if you have only one opened window with Chrome (for example), the browser will be closed.

If you have multiple windows opened, only the window where the function is executed will be closed.
