How can my web page open a new tab in a separate process?
Google Chrome has a multi-process architecture, meaning tabs can run in separate processes from each other, and from the main browser process. New tabs spawned from a web page, however, are usually opened in the same process, so that the original page can access the new tab using JavaScript. If you’d like a new tab to open in a separate process: • Open the new tab with about:blank as its target. • Set the newly opened tab’s opener variable to null, so that it can’t access the original page. • Redirect from about:blank to any URL on a different domain, port, or protocol than that of the page spawning the pop-up. For example, if the page spawning the pop-up is on http://www.example.com/: • a different domain would be http://www.example.org • a different port would be http://www.example.com:8080 • a different protocol would be https://www.example.com Google Chrome will recognize these actions as a hint that the new and old pages should be isolated from each other, and will attempt to load
