Accessibility New Window Warnings


Web Content Accessibility Guidelines (WCAG) Success Criterion 3.2 (Predictable) specifies that web pages should appear and operate in predictable ways. It is a common practice to set links that go to off-site locations to open in a new window or tab when clicked. Opening new windows or tabs automatically when a link is activated can be disorienting for people who have difficulty perceiving visual content, and for some people with cognitive disabilities, if they are not warned in advance.

This plugin helps websites become more accessible and better meet WCAG guidelines for predicability by providing advanced warning if a link is going to open a new window or tab before the user clicks or activates it. Providing a warning allows the user to decide it they want to leave the current window, and the warning will help them find their way back, if they do decide they would like to go to the new window. It will help them understand that the “back” button will not work and that they have to return to the last window they had open, in order to find their previous location.

There are no settings in this plugin. Simply activate it and it will automatically find all links that open in a new window and add the following three fixes to each link:
1. A new window icon after the link text to denote that the link opens in a new window for sighted people.
2. A tooltip, visible on hover, that says “opens a new window.”
3. “Opens a new window” screen reader text that will be read out to blind or visually impaired people using screen readers immediately following the link anchor text.

Please note: new window warnings will be added to links and links that have been styled to look like buttons, including social media sharing and link icons. Depending upon what third party plugins are adding links to your site that open in new windows, some CSS styling may be required.

In addition to adding warnings for your users, this plugin integrates with the Accessibility Checker plugin; when Accessibility New Window Warnings is activated, it will automatically clear all “Link Opens New Window or Tab” warnings in Accessibility Checker scans of your website. Installing and activating this plugin is a great way to quickly remediate and remove a lot of open issues across you entire website.

The Accessibility New Window Warnings plugin is inspired by Techniques for WCAG 2.0 G201: Giving users advanced warning when opening a new window.


The Accessibility New Window Warnings plugin is ready for localization. We have added a Spanish translation and are open to more translations!

How does the plugin know which links open new windows?

The plugin looks for target="_blank" in your links. If target="_blank" is present then it will identify the link as opening a new window and automatically add the warning.

Is this compatible with the block editor or the classic editor or page builder XYZ?

Yes. No matter how you’re creating your content, this plugin will work. It uses javascript to identify the links and fix them as the page is rendered so it doesn’t matter what tool you used to build out your content.

The plugin adds new window icons to my social media icons and I don’t like how it looks!?

When it comes to accessibility, warning users about links opening in new tabs or windows applies to all links, not just links in your body text. Adding the visible icon is important for users with cognative disabilities or mobility challenges so they are warned about the new window before clicking on or activating links – it’s not sufficient to just add screen reader text for blind and visually imparied users.

Depending upon how you’re adding linked icons, we understand that this can cause a less than ideal appearance. If you don’t like how the visible icon appears you have a couple of options: either change the link to not open in a new window or change the design of your social media or icon buttons either with that plugin’s settings or custom CSS. It’s generally not considered correct to hide the visible icon.

Does this plugin make my website accessible?

This plugin can help to make your website more accessible by fixing a common issue, however it alone will not make your website accessible. True accessibility requires manual and automated testing and a human being making fixes in the website. While problems can be resolved with an automated tool such as this, not all accessibility problems can be identified automatically.

In addition to accessibility, I use for all client sites that provide robust external resources for their customers, simply as info/warning, but also, to support rural, area internet visitors that work on desktop, open a variety of tabs and do not wish to keep doing page reloads, especially for dynamic, un-cached information pages. It’s a way to save people from ‘right click’ choose option, time, as well. 😀

This is great! Thanks for making available a quick way to address WCAG 3.2 (Predictability) on those unavoidable “_blank” tags, while still supporting users’ rights to know that clicking a link is gonna take them on a trip to another window.

This plug-in does insert a “opens in new window” icon next to all hyperlinks, which can seriously impact your social icons and menus. I used CSS to remove the icon, but left the title tag in place. Unfortunately, it still left the space after the hyperlink causing the blue underline to continue until it hit the next word.

I am so happy I went to WordCamp PHX and met Amber Hinds! She told me about her company’s plugin accessibility-new-window-warnings which is exactly what I have been looking for! A simple plugin to let visitors know that a link is about to open a new window. Just install it, activate it and it works! thanks to everyone on the Equalize Digital team for making it easy to make websites accessible! -Christina Hills
