The following pages are for debugging purposes only. Since they cause the renderer to crash or freeze, they are not directly related; you can type them into the address bar if you need them.

chrome://private-aggregation-internals/ Private aggregation API internals

chrome://badcastcrash/ The browser crashes due to a bad cast.

chrome://inducebrowsercrashforrealz/ Intentionally causes the browser to crash.

chrome://inducebrowserdcheckforrealz/ Intentionally causes a browser CHECK.

chrome://quit/ Quits the browser.

chrome://restart/ Restarts the browser.

chrome://omnibox/ In Google Chrome, the Omnibox feature combines the browser’s address bar and search box into one area at the top of the browser window. You can also use it to bookmark websites and view security information about your current web page. When a user enters your extension’s keyword, they interact exclusively with your extension. Each keystroke is sent to your extension and you can provide suggestions in return

chrome://media-engagement/ As you may have noticed, web browsers are moving towards stricter autoplay policies to improve user experience, minimize incentives to install ad blockers, and reduce data consumption on expensive and/or limited networks. These changes are intended to give users greater control over playback and benefit publishers with legitimate use cases.

Automatic playback with mute is always allowed.

Autoplay with sound is enabled if:

The user interacted with the domain (click, tap, etc.).

Desktop has exceeded the user’s Media Engagement Index threshold, which means the user has previously played a video with sound.

The user has added the site to their home screen on their mobile device or installed the PWA on their desktop.

Top frames can delegate autoplay permission to their iframes to allow autoplay with sound.

chrome://password-manager-internals/ It captures and displays logs of Chrome’s password manager. The password manager has become a standard feature of Chrome, so having an event log can help developers fix bugs.

chrome://predictors It lists all possible keyword strings that can be used to predict websites. The most interesting thing is that Chrome keeps a log of visits and misses in the form of a table, and you can see it right here with all the rows of the website.
