Hidden configuration pages offer more settings in Chrome, Firefox
Google Chrome & Mozilla Firefox browser includes a Developer Settings page, which contains numerous flags, which you can enable or disable. Most of the settings here are meant for advanced users and developers, and should not be normally be touched by common users, as they are usually configurations meant for developers or contain features that are currently in the experimental stage.
To search for a setting, it is best to press Ctrl+F and use the Search or Find bar which appears on these pages.
