You can modify Firefox with and extension, I personally would not want that at all, before dismissing a tab I make sure there is nothing in the tab in a backward direction, and the and would consider looking a anything but a blank page for a new tab as an encumbrance but you can do what you ask for. New Tab Home Page: * https://support.mozilla.com/questions/837330 * https://support.mozilla.com/questions/840344 ---- New Tab Home Page has not been updated use this instead *'''NewTabURL''' :: Add-ons for Firefox<br>https://addons.mozilla.org/firefox/addon/newtaburl/
