Sorry, first time using these, I got ya! I was using FireFox but starting in August 2016 they are blocking Flash Player. That might be why. I don't know, but mine would not work so I moved to ME....

The link was not just for Firefox, It is for Hidden configuration pages offer additional settings for Edge, Chrome, Firefox browsers...

I was having problems also, I found a page about Hidden Microsoft Edge Settings, worked for me. Hope is helps.
