WPF GeckoBrowser Not able to load url in the windows browser

WPF GeckoBrowser Not able to load url in the windows browser
I am using gecko web browser for my WPF windows application. We have a particular URL which is opening in all the system browser but not working on the windows browser.But we use any other it loads. When contacted the support team they were saying need to enable javascript. So please help me how to enable the javascript in gecko browser. Or there is any way to resolve. The URL is asking for the notification of location in the system browser(Google Chrome, Edge, Firefox).
The URL load is the partial load. we are getting the background related UI for the URL. The body part of the url is not loading
I have used inbuilt .net browser but that URL is not loading in that application also.
