## Description

**JavaScript Errors Notifier** is a Chrome extension designed to help developers quickly identify and resolve JavaScript errors on any webpage. It enhances debugging by changing the extension icon color in the toolbar whenever a JavaScript error occurs, showing an error icon in the page corner, and providing detailed error information through clickable popups.

Key features include clickable error source URLs, stack trace visibility, handling of console.error calls, detection of missing files (JS, CSS), and ignoring duplicated or irrelevant errors such as those from AdBlock or other Chrome extensions. It also offers quick access to search errors on StackOverflow and allows copying error details to the clipboard, making error management intuitive and efficient.
