Question

I progammed a program that you clicked a button and it opened google. And I put into google window "back" pushbutton when I push button it's switches to previous screen but when I looked task manager there is google tab still open how can I close it?

Please trim your code to make it easier to find your problem. Follow these guidelines to create a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example). — Community, Sep 16 '22 at 16:12
Despite what suggested by the tutorial you're following, you should **not** continuously add widgets to the QStackedWidget, which fundamentally works like tab widget, but without tabs: you don't add new tabs, you switch them. See the last part of [this answer](https://stackoverflow.com/a/69534216). Then: 1. don't add QDialog (or QMainWindow) to QStackedWidget, they're intended as top level windows, use QWidget; 2. ignore that tutorial, as it suggests *a lot* of terrible bad practices. — musicamante, Sep 16 '22 at 18:10
You must *never* create more than one instance of `QApplication`, so remove `qt_app`. Then move the `if __name__ == __main__` statement to the bottom and put the last block of code inside it. Also, never use a bare `except`, as it makes debugging unnecessarily difficult - you ***need*** to see those tracebacks! — ekhumoro, Sep 16 '22 at 18:18
