No Opener, No Phishers

It would have been nicer if the extension allowed making exceptions for some sites via a whitelist.

PSA: This is no longer required if you're on version 88 or newer on any platform that uses Chromium (e.g. Chrome, New Edge, Brave, etc.). https://www.chromestatus.com/feature/6140064063029248

This feature is now baked into Chrome so the extension can be removed for most purposes. Where a site links to a target other than "_blank", e.g. "_potato" the same security issue still exists. Not sure if this extension only works with _blank links

No longer needed since Chrome 88! (see crbug 898942 for details) Thanks for creating this extension.

Simple and effective. Successfully tested at https://mathiasbynens.github.io/rel-noopener/ in Vivaldi 2.10.1745.27 (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.131 Safari/537.36).

works fine and nice extension!

This does exactly what you'd want and expect it to do. The actual code is a single line of JS to simply add the 'noopener', and 'noreferrer' attributes to all links with a target of _blank. It's a clean and simple extension that should be baked directly into Chrome itself.

It does what it says. You can check (and better understand) its effectiveness on this website: https://mathiasbynens.github.io/rel-noopener/ Thanks Jamie.
