Minefield and SuperBar

Anybody else have a problem where Mozilla Minefield when opened from the superbar, creates a second icon on the superbar...rather than using the first icon and it minimizes to the second icon as well....leaving 2 icons in the Superbar?

I've Googled a bit, but not finding much.

Oddly enough, I managed to fix it. I started Minefield so that the icon showed in the Taskbar, I right clicked and said Pin to Taskbar. Then I deleted my original icon, closed Minefield and reopened and now it's using the new icon.

thank you so much, was annoying me to no end
