## Description

Check iframe is a Firefox extension that helps you identify iframe and frame usage on any web page. It indicates the presence and type of tags by color-coding the icon (gray for unchecked, green for no tags, orange for tags detected, purple for a source match). The extension can also scroll to the relevant elements and highlight them with a red border for quick inspection.

It includes an optional redirection feature to automatically navigate to the first iframe source on configured sites. Setup and usage are documented with links to the official docs and the GitHub repository for easy configuration and customization.
