Add code to the userContent.css file.

• http://kb.mozillazine.org/userContent.css

@-moz-document url(about:home){
 #topSection + spacer, #launcher { display: none !important; }
}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

• http://kb.mozillazine.org/Editing_configuration

• create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
• use a plain text editor like TextEdit to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
• paste the code in the userContent.css file in the editor window

You can use this button to go to the current Firefox profile folder:

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

This will need less technical experience with Firefox and computers than what cor-el posted.

Install the Stylish extension. https://addons.mozilla.org/en-US/firefox/addon/stylish/

Then install this User Style which will hide the area (known internally as "snippets") which is below the search container on the default homepage. https://userstyles.org/styles/104618/about-home-hide-snippets
