Follow these steps to set your custom Frontpage (or any other URL) as the default "New-Tab"-Page in your Chrome Browser:
1. Install the "Custom New Tab URL" Extension
There are several different free Extensions which do the same thing. We like this free one and will show you how to use this one. If you choose a different one the steps may be a bit different.
First of all you need to install the extension by opening Chrome and navigating to this page on the Chrome Webstore. Once you clicked on "Install", the Extension will be added to your Chrome browser.
2. Configure the Extension
The first time you open up a new Browser Tab and you'll see a "Custom New Tab URL" Configuration page.
If Chrome asks you if this is the expected page, click on "Keep these changes".
Now, click on "Options page" and check the check-box next to "Enabled". Enter the URL of your Frontpage, e.g. "https://myfront.page/example" and press "Save" and you are ready to go!
Now open up a new tab again and you should see your custom Frontpage! If Chrome asks you again if this is the expected page, click on "Keep these changes".
Whenever you open up a new tab in Chrome from now on, you will be greeted with your custom Frontpage! Awesome!
