I'm customizing my desktop based on the one that I saw yesterday at howtogeek. As you can see I am able to change the icon of Firefox, but when I launch it, it opens another one (I now have two Firefox icons on the taskbar). What do I do so that when I click the one that is pinned on the taskbar, it doesn't open up another?
And how do I change the Chrome icon when I launch it? They're both portable.
