This page collects scenarios where browsers might show modal dialogs or open auxiliary windows. Use it to observe how your automation tooling handles blocking dialogs, confirmation prompts, and windows that appear when you close an overlay or attempt to leave the page.
Each native dialog blocks JavaScript execution until you dismiss it. We log the results below to make the blocking behavior obvious.
The custom dialog mimics a UI-driven modal. Dismissing it can launch a new window if the relevant automation toggle is enabled.
Pop-up blocked. Most browsers only allow automatically opened windows when they follow a direct user gesture.
These pop-up attempts stay within this origin by creating a blank window and writing simple content into it. If the browser blocks the action, we log that below.
