Firefox logo has changed in dock and in applications folder (Mac)
I saw that other people had a similar problem, the logo's changed in the dock to a generic Mac applications icon. But the usual solution isn't working, because the logo's changed in the applications folder as well! So when I remove it from the dock and drag and drop it from the folder, there's no change!

Try to uninstall (drag the Firefox application to the Trash) and reinstall Firefox.
