I teach online and my send/submit buttons are at the bottom of each page. When a page opens in a child window, it opens too big, so that the button is below my lower toolbar. I have to re-size the window every time to operate.

Firefox usually only opens a window in a pop-up window if there are dimensions for a window specified.

You can either choose to open that window in a tab instead and disable the advanced JavaScript that allows websites to set windows dimensions to avoid changing your current window.
