Something weird has happened to my taskbar. I have a few programs pinned there and everything was okay. Then today I unpinned Firefox from there because I wanted to change the icon I was using. After deciding I didn't like it I tried to go back to the one I was using but when I pinned it back to the task bar this problem occurred:
As you can see when I click on the silver Firefox icon, it opens up a new firefox icon (default icon) in a separate place, taking up unnecessary space. I can't figure out how to make it go back to the way it was where everything stayed within the silver icon.
