Cyrillic Killer

🚫 Cyrillic Killer is a browser extension designed to help users stay focused by automatically blurring all Cyrillic characters on web pages. It is ideal for language learning 📘, reducing distractions 🧠, or filtering specific types of content. The extension works seamlessly in the background and allows users to manage site-based exceptions. ✨ Key Features 🔤 Automatic Cyrillic Detection The extension detects and blurs all Cyrillic characters (Unicode range U+0400–U+04FF) on any website. It works with both static and dynamic content, including modern web applications built with frameworks such as React and Vue, and also supports Shadow DOM for full coverage. 🌐 Smart Site Exception Management Users can easily add websites to an exception list to disable blurring on selected domains. Wildcard domain patterns (for example, *.example.com) are supported. A one-click toggle allows adding or removing the current site, and all preferences are stored persistently across browser sessions. 🎨 Modern and Intuitive Interface The extension provides a clean and modern popup interface for managing site exceptions. It includes real-time site detection and clear visual feedback about whether the current site is excluded or affected. ⚡ High Performance Cyrillic Killer is optimized to minimize performance impact. It uses debouncing to prevent slowdowns, intelligently avoids interfering with text input fields, and manages memory efficiently to keep page load times fast. 🔒 Privacy and Security All data is stored locally in the user’s browser. The extension does not use external servers, does not collect personal data, and does not include tracking or analytics. 🛠️ How It Works The extension scans web pages in real time to detect Cyrillic characters, wraps the detected text with CSS-based blur effects, respects user-defined site exceptions, and automatically adapts to dynamic content changes on the page. 🎯 Use Cases 📖 Language learning by focusing on non-Cyrillic content 🧠 Improving productivity by reducing visual distractions 🎛️ Custom content filtering based on personal preferences ♿ Accessibility adjustments for better content visibility 📦 Installation and Usage Install the extension from the Chrome Web Store Click the extension icon to open the popup Manage site exceptions if needed Enjoy a more focused browsing experience ✨ ⚙️ Technical Details • Manifest version: 3 • Permissions: storage, activeTab • Compatibility: Chrome, Edge, and other Chromium-based browsers • Performance: optimized for low resource usage
