Back in 2018 Apple changed the way in which Safari treats all HTML links that use the target=“_blank” attribute to make it so that they automatically imply the noopener attribute. Once enabled, this feature prevents embedded links from redirecting to a different URL.
Microsoft Edge developer Eric Lawrence recently added this exact same feature to Chromium which means that it will soon find its way to Google Chrome, Brave, Vivaldi, Microsoft Edge and all other Chromium-based browsers. Lawrence provided further details on how this feature will work in Chromium in his commit, saying:
“To mitigate “tab-napping” attacks, in which a new tab/window opened by a victim context may navigate that opener context, the HTML standard changed to specify that anchors that target _blank should behave as if |rel=”noopener”| is set. A page wishing to opt out of this behavior may set |rel=”opener”|.”
