Everytime I went in to a webbpage that was using Adobe Flash Player I got the pop up telling me that This webpage wants to run the following add-on: Adobe Flash Player.
I pressed the Allow button and it was coming back again and again.
The solution for me was to enable ActiveX Filtering in IE 11.
- When you have IE 11 open press the Alt button to get to the Tools menu.
Click on ActiveX Filtering.
- Restart your browser.
I hope it works for you to.
