To prevent this, version 0.3.3 introduced a new feature in the right-click context menu to return an actual window object when a script is not releasing the loop. This loop is not going to be released and hence the user cannot access the website content until a popup is shown. Some malicious scripts validate the returned window object and if the object is not an actual window they just request a new popup. When a popup is requested by a page, this extension returns a normal JavaScript object instead of the actual window object and records all the actions that are called in the returned object. What is the newly introduced feature "Open shadow window on popup request" which is added to the right-click context menu over the toolbar button?
