So I am trying to login to a site that has it's first login through a popup window, as soon as you visit it, it brings a popup window that requires a User name and password. Now i have a very rough idea on how i would do this if it wasn't a pop up window, but because I don't know how to see the HTML code of the window, i don't know what to put in to driver.findElement(By.id("")) .
Sorry in advance if this is all too vague .
