Deleted new weather widget but horizontal space at top of home page remains

Greetings... I successfully deleted the new weather widget that appears at the top right of my Firefox homepage but the horizontal space at the top of my homepage remains. I followed all of the steps (3) to delete the weather widget but none of them also deleted the horizontal space. As a result, there is a wide white top "margin" that appears on my homepage, below which the customary Firefox graphic logo appears. On my Firefox homepage, I have three rows of shortcuts that now appear lower on the homepage and a vertical scroll bar now appears on the right side of the homepage. Before the new weather widget appeared on my homepage, the three rows of shortcuts were vertically centered on the homepage, without the need for a vertical scroll bar to appear. Either there is a way that the horizontal space at the top of my homepage can be deleted, or I will have to resort to creating a custom HTML webpage containing my shortcuts. Please advise which solution will resolve this problem. Thank you very much for your time and feedback. Take care...
