I'd like to make my own new tab page, and replace the old new tab page with it. This could be done by simple replacing the default new tab, or by redirecting to a specific page when opening a new tab.
I'm looking for a way to do this without installing any extensions, because my employer blocks any purchases/installations from the Chrome Webstore.
about:flags
(the closest thing to Firefox'sabout:config
) but it doesn't seem to have anything related to this.
