Definitely not. I cannot advise how to change MAC, but know that software isn’t needed for any of those things. You should be able to delete cookies and history from your browser settings. If you are using a disposable or Tor, they should not persist anyway. I saw a post about MAC that may help on that part of the issue. https://forum.qubes-os.org/t/anonymizing-your-mac-address/19072
