I am using an Apple Mac Mini OS is 10.13.6. My default browser is Firefox 65.0.1. I also have the Opera browser installed in the Applications folder.
When ever I drag a URL to the Desktop the Icon shows as a white Icon with a red "O". When I right click on the Icon and go to Get Information the URL has .WEBLOC and the Change is greyed out. I am aware that the .WEBLOC is the result of Safari being installed and integrated into the OS by Apple, but why am I not getting a Firefox Icon (which is the default) on the Desktop instead of the Opera Icon?
I have checked & confirmed that Firefox is set as the default browser in both the OS System Preferences as well as in FF Preferences.
