When opening a new window on firefox I see a "homepage" offering some shortcut icons along with headings, i.e. : Popular Today, Connections, etc., stories to click on. How can I eliminate these options from being "offered" or shown? Many thanks!

When opening a new window on firefox I see a "homepage" (No URL offered at the top of the page), offering some helpful, frequently used shortcut icons followed by a number of headings, i.e. : Popular Today, Connections, Featured Videos, etc., providing image/links to stories from various "news" or "interest" websites, which I can click on to view. Opening a number of these sites in order to view the advertised "story" require setting up a free, or paywall account/membership, etc.. How can I eliminate these undesirable/unwanted options from being "offered" or shown on my firefox homepage? Something may look interesting, but I'm not one to sign up, or pay to view these opportunities. I see where I can eliminate entire Categories, but what I'm trying to do is block, or eliminate the "offer to view" what I deem "unwanted offers to sign up to view this "story". Can this "Junk/Bait" be eliminated from my homepage on a site by site basis? As examples: CNN, Wired", "the cut", among others. Can the page be configured to eliminate the offering of "Non-Free", "Non-Membership", "Non-Signup" Sites? (Apologies for my lack of appropriate semantics, I'm just a user, not an Internet Expert, developer, or or software-savvy person.) As an aside, is there a way to contact a real live human person at Mozilla/Firefox to assist with issues like this, or answer related questions. All I seem to find are circular links to "Contact Mozilla", which bring me to unrelated FAQ databases, and user forums, etc., where I find I'm unable to get an answer to the question asked? Thanks for reading and advising!
