# Cyrillic URL Detector
A browser extension that helps protect against phishing attempts by detecting Cyrillic characters in URLs.
## Features

- Warning can be dismissed with a close button

## How it works
The extension monitors the URL of the current page and checks for the presence of Cyrillic characters (Unicode range U+0400 to U+04FF). If any are detected, a red warning bar appears at the top of the page to alert the user of potential phishing attempts.
