In the latest version of Firefox, is there a way to make the top pages boxes on the new tab page larger? In this version, there is also more of them. I had the perfect number of pinned sites to fill them in the last version. Is there a way to set the exact number of pages shown. I need more than one row, but less than two and I don't want to just pin stuff to the extra boxes nor do I want to have every page I visit displayed every time I open a new tab.
