I would like to further customize my new tab page. Specifically, I'd like to get rid of the firefox logo at the top, and I'd like to increase the number of columns of shortcuts per row from 8 to lets say 14, while decreasing the spacing between each icon by about half. I've already followed [[https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_show-more-or-fewer-shortcuts|this tutorial]] from y'all on how to increase the number of rows, and another tutorial that had me fiddle with the browser.newtabpage.activity-stream.topSitesRows setting directly in my about config. I have enough rows I want more columns and less space between them. Find attached the current state of my new tab page, with my particular shortcuts redacted, and the number of additional shortcuts I could fit on the page without adjusting the gabs between them or resorting to a scroll bar. I'm missing out on at least 44 short cuts due to the default constraints, which I've been unable to find working overrides for. Depending on how cut-throat I get with my thin-margins, I could potentially be missing out on up to 80. I tried following the near identical instructions from both this [https://superuser.com/questions/1288920/how-to-modify-the-new-tab-page-in-firefox-with-stylish stack exchange] and this [https://www.tutorialpedia.org/blog/how-to-change-new-tab-background-firefox-css/ tutorialpedia article], to try and get at the problem by modifying my about page's CSS; but I was unable to change part of the page's appearance. Not even the background or text color. Is the information in these out-dated (the stack-exchange is 7 years old) or otherwise inaccurate; or is there perhaps a setting in firefox which is interferring with these tutorials' solution method. I have already tried resetting firefox with extensions disabled to check if any of my extensions are causing the problem to no discernable affect.
