Stackoverflow, but here you go.

I've made a userscript that puts a rel="noopener" on target="_blank" links where missing, with no issues for about half a year usage. While noreferer breaks some payment processors and the like. Sadly, i lost it a few months ago, need to redo it sometime.

the answers say these are not recommended anymore, because browsers changed their defaults a long time ago

Thanks, really good to know.

For quick reference, here is the first section from the MSDN docs:

The noopener keyword for the rel attribute of the <a>, <area>, and <form> elements instructs the browser to navigate to the target resource without granting the new browsing context access to the document that opened it — by not setting the Window.opener property on the opened window (it returns null).
