Reduce the risk of falling victim to phishing attacks.

No Opener, No Phishers
Description from store

Any website that uses target="_blank" on their links, allows user generated content and doesn't use the rel="noopener" attribute on their links (I'm looking at you Facebook, Twitter etc.) is vulnerable to a scarily simple phishing attack.

For an example of this kind of attack, view this example that I've made: https://jamiefarrelly.github.io/Rel-NoOpener-Example/

This Chrome extension is as simple as it gets, all it does is add "noopener noreferrer" to the rel attribute on all links on the pages that you're visiting so that you won't fall victim to this type of phishing attack.

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

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.
