Hi Richard,
We referred the below MSDN blog and it says when Add-on is registered with AppContainer compatible flag it will be loaded in IE ,
Browser Helper Objects (BHO) or toolbars load when the browser starts. With AppContainer is turned on, IE11 checks the add-on registration for an AppContainer compatible flag. If it's present, the BHO or toolbar loads and runs. If it isn't present, the BHO or toolbar is blocked, and the user is notified of the EPM incompatibility. When a webpage loads an ActiveX control, the CLSID registration for the control is checked for an AppContainer compatible flag. If the flag isn't present, the user is notified that the control isn't compatible. If the user trusts the site, they can click a button to turn off EPM for the current site.
How to enable Addon with AppContainer Flag Enabled in Firebreath project.
We followed the Steps provided in the Topic[Issues With Internet Explorer Enhanced Protected Mode] in below firebreath website and we tried to register the Plugin but still not loading in IE , Can you please elaborately explain the steps mentioned here and it will be really useful.
Thanks & Regards,
Gopinath R
