IceDragon Always Opens A Second Instance

I’m using IceDragon on Win 10 Home 64 Bit. I have McAfee installed. Whenever I launch IceDragon, it opens up a second instance and the main instance pinned to my taskbar does not open…This new instance cannot be pinned to Taskbar like the Main one. I tried unpinning ID, shutting down my computer for a few hour,s and repinning it again. But it always opens a second instance.

I'm not quite sure what these mean ---> second instance, main instance, new instance, main instance Could you reword or rephase on what your asking please :) To My Best Guess, Are you having issues with the IceDragon Icons not working?

On the Taskbar, I have pinned IceDragon. When I click on it’s icon, it opens IceDragon into a second icon on the far right of every icon on my Taskbar. That icon is the only usable IceDargon I have. The second icon has a fully functioning IceDragon running. The first one does not. This new icon doesn’t have right click capabilities. No jump list. Can’t be pinned/unpinned, etc. Only shows a preview of the current tab I’m in. It can be moved around. I’m looking for a way to open IceDragon in the pinned icon. Not by creating a new IceDragon icon.

Two IceDragon icons on my Taskbar:

Try unpinning IceDragon. Then start IceDragon from the shortcut on the desktop and pin it. Does that help?

That worked. Thanks.
