What is rel noopener?
Make links to cross-origin destinations safe
In HTML, link types indicate the relationship between two documents, in which one links to the other using an <a>, <area>, <form>, or <link> element. When you open another page using target="_blank", the other page may run on the same process as your page, unless Site Isolation is enabled. The other page can access your window object with the window.opener property. This allows other page to redirect your page to a malicious URL - see About rel=noopener for more details. [Read More]
