I was thinking about changing the firefox icon, and I found a couple icons I wanted to try out, but the usual copy/paste in the info window wasn't working. I went in to the package contents to just replace the icon file, but found all the package contents was read only, and locked so I can't change it to read/write. Any suggestions on how I can unlock it or change the icon in another way? I'm running Tiger 10.4.11, and it's Firefox 2. I've attached a screenshot of the section of the info box that shows that it's read only and locked. I have admin privileges if that helps.
