4a. Do I "Paste" and Delete All of the Old Code?
  4b. Do I Add the Copied Code? if so then "Where" do I add the Code i.e. Top, Middle or Bottom of Code?
  4c. Where/Which File do I modify?

1. Your "Help" tells me the "Answers are no longer up to date". Are there any Updates? 2. Why have you abandoned users who want their "Tabs" Down instead of at the Top? 3. I do not Know How To Code, so your answer is for me to Understand Code?! 4. You instructions say to "Copy" the code. They do Not say what to do next! 4a. Do I "Paste" and Delete All of the Old Code? 4b. Do I Add the Copied Code? if so then "Where" do I add the Code i.e. Top, Middle or Bottom of Code? 4c. Where/Which File do I modify? I used to Love Firefox. Now Not So Much.
