I tried to fix the “most visited” grid situation on my new tab page (I had an extension to remove it but it stopped working when content scripts are disabled on the new tab page in Chrome 61) but failed. Here is my failed attempt in case anyone’s interested. (It works, but has unbearable flaws.)
Since I can’t replicate the default new tab page, and a completely blank NTP is too bland for my taste, I decided to let
fortune(6) give me something random each time. Here is the extension: https://github.com/zmwangx/Fortune.
