No Opener, No Phishers Extension

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.

Gaurav (ID: 0000004e80adac64) Voted 5 ★ - Updated 09/11/2022 It would have been nicer if the extension allowed making exceptions for some sites via a whitelist.

Justin Butler (ID: 00000024a5afafb6) Voted 3 ★ - Updated 06/29/2021 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

icon

Sam Prince (ID: 1c9d88fe1ba5e151) Voted 5 ★ - Updated 02/01/2021 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

Madis (ID: 000000e51ea8f766) Voted 5 ★ - Updated 12/05/2020 No longer needed since Chrome 88! (see crbug 898942 for details) Thanks for creating this extension.
