how to stop a news agency articles from my firefox home page since they require paid membership

Very many news agencies now require paid subscription to read their articles. I don't want to see those companies lead in for articles in my Firefox home page. Google news home page (news.google.com/home) has an option and others by clicking the three dots ... to the right of article title lead in. There are multiple choices offered among those options is: HIDE ALL STORIES FROM ------ (it doesn't name the news agency because it is to the right of that SPECIFIC article). Presto no more show up in news.google.com/home. Now that more and more news vendors require paid subscriptions to read even their first article it is a great feature I have used for years on news.google.com/home. But now I am regularly using Firefox home page and sure miss that feature. Finally I wish I could afford to pay for so many and truly there are now many require paid subscription to read even the first article. Others let you read one. Anyway thank you for your consideration. I think it provides a competitive edge if not overwhelmingly complicated to enact.
