Is there any kind of API that can allow me to manipulate a file download dialog in Firefox? (I want to access the one that appears when user does something, not initiate one
Most browsers (in mine case Firefox) select the OK button by default. So I managed to solve this by using the following code. It basically presses enter for you and the file is downloaded.
Robot robot = new Robot();
// A short pause, just to be sure that OK is selected
Thread.sleep(3000);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
