Hello, Zooming doesn't change tile sizes for you on the new tab page? Just to be clear about the zooming feature: * To make things bigger, press '''Ctrl''' and '''&#43''' at the same time. * To make things smaller, press '''Ctrl''' and '''-''' at the same time. * To reset the size back to normal, press '''Ctrl''' and '''0''' at the same time. You can also see '''jscher2000''''s Chosen Solution here: https://support.mozilla.org/en-US/questions/1025414 It requires the [https://addons.mozilla.org/firefox/addon/stylish/ Stylish] add-on but will automatically shrink the tiles on the page so that more appear: * https://userstyles.org/styles/106326/shrink-new-tab-thumbnails Unless you have an extension installed that changes the new tab page, changing the zoom level for the page will change the size of the tiles and show more. The limit is set to 3 rows by 5 columns by default (if you zoom out the page/shrink the tile sizes sufficiently, the number of tiles are limited to that setting). If you want to change those values: # In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''. The about:config "''This might void your warranty!''" warning page may appear. # Click '''I'll be careful, I promise!''' to continue to the about:config page. # Search for and modify the preferences (by double clicking the row, or right clicking the row and selecting '''Modify''') #* '''browser.newtabpage.columns''' #* '''browser.newtabpage.rows'''
