The about:home page and the about:newtab page are the same Firefox Home page with the tiles, so it doesn't (shouldn't) make a difference which you use to get this Firefox Home page. In a long past those were different pages, but currently this is no longer the case. *https://support.mozilla.org/en-US/kb/customize-new-tab-page *https://support.mozilla.org/en-US/kb/hide-or-display-content-new-tab
