Customize the new tab URL.
Chrome does not let you customize new tab page. The new tab page always opens a custom Google Search page and chrome extensions do not work on this page.
This extension lets you point the new tab page to a URL of your choice. It can just be Google.com, your company's homepage or simply a blank page. It is lightweight on your browser (<50kb - compared to for example Grammarly which is 36MB), has no tracking and is straight-forward to use.
If you at anytime want to disable custom new tab, you can do that by going to chrome://extensions and disabling this extensions.
