I’m adding videos to a page but when a user makes click I want it to open a new window (or tab) not to open in the same active window.
How can I achieve this?
You can simply just add target="_blank at the anchor. If you mean at homepage which is built with page builder you can add target="_blank" on kensington/inc/page-builder/components/videos/front.php , go to line 21 then add target="_blank".
It should look like this
