I may be dumb but I don’t know how to get the application “FirefoxNightly” so I can’t reach the real window.

Given what I see on other Firefox windows, I’m not sure that what you try to reach is a true button.

Hi there,

Have you tried something like the PreFab UI Browser or UI Element Inspector to get a more precise reference to the button you’re trying to click?
