I want the default photos to be removed, so I switched off “Show Background Image”. The new-tab background was then replaced with the bright gradient purple-orange color, which bothers me more:
Can I make the default background color simply black or dark grey? I found an article that also described this issue, but the solution provided by NickWoolsey is no longer valid:
“Preferences -> General-> A new tab shows… Change that to “blank” and you will get a blank grey page :)”
