Popup Tab Switcher is an extension for Chrome that allows you to easily switch between open tabs, and do it in a way that is similar to using a tab in a desktop browser.

You can also use it as a workaround for a problem that some websites have with rendering their content in the same window. It can also be used to make sure that the content of a page doesn't get hidden by another page that is loaded in the same window.

To use Popup Tab Switcher, you need to first set the shortcut key to the Alt key (the default key is the Y key).
