I followed the links and made changes accordingly. I got the National Weather Service to work, but each time I have to allow the site to use flash. No big deal that is how it worked with Edge as well.
The Cox site where I use Contour to watch cable TV on my computer still isn't working. I made the same changes to it that I made to the NWS site but I am getting this error code: Error (ftde.xact.3307.1107296347)
