i disabled the security center "Microsoft.Windows.SecHealthUI_cw5n1h2txyewy"
completely and tried it again but still no plugin

i had only download helper installed in firefox
no difference without that

i installed avast and selected the plugin in the options during install
after that it looked like the screenshot bob postet
