open any hyperlinks with a noopener attribute

Why use noopener?

Performance
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. If the other page

is running a lot of JavaScript, your page's performance may also suffer. See The

Performance Benefits of rel=noopener.
Security
The other page can access your window object with the window.opener property.

This exposes an attack surface because the other page can potentially redirect

your page to a malicious URL. See About rel=noopener.
Recommendations
Add rel="noopener" or rel="noreferrer" to each of the links that Lighthouse has

identified in your report. In general, when you use target="_blank", always add

rel="noopener" or rel="noreferrer".

-- Google Developers

The most obvious effect is that the page loads much faster than that the

"noopener" is absent.
