Hi, you can change the number of tiles on the New Tab page by zooming in or out (Ctrl and + key, or Ctrl and - key). You may also want to keep the same zoom setting when clicking on a new tab: Type '''about:config''' into the address bar, press Enter, accept the warning, scroll down to '''browser.newtab.preload''' and double click on it to change 'Value' from True to False. It is also possible in 'about:config' to change the maximum number of tiles, by scrolling down to '''browser.newtabpage.columns''' (or '''.rows'''), then right click > Modify, to set a new number in 'Value.'
