Marks: 文本高亮器 作者： Myoungdo Park

Marks: Text Highlighter is a powerful, privacy-respecting Firefox extension that enables users to highlight and manage text on any web page. It is designed to boost productivity, improve reading workflows, and provide a seamless way to revisit important content — all without ever sending your data to external servers.

🔍 Key Features
✅ Multi-Color Text Highlighting
Select text on any website and highlight it with your preferred color. The extension offers five distinct highlight colors — yellow, green, blue, pink, and orange — so you can organize and categorize content visually.

⚡️ Quick Highlight via Context Menu or Shortcut
You can highlight selected text instantly using:
- A right-click context menu
- Customizable keyboard shortcuts (Ctrl+Shift+1 through Ctrl+Shift+4, etc.)

These actions work even across multiple tabs and sessions.

🗂 Highlight Management by Page
Every highlight is stored and associated with its respective URL. Reopen any highlighted page later, and all your highlights are automatically restored. You can:

• View a list of all your highlighted pages
• Review, edit, or delete individual highlights or entire groups
• See metadata like page titles and last updated time

🧭 Minimap View for Navigation
A built-in "minimap" appears on the right edge of the page, showing markers for all your highlights. This helps you:

• Instantly locate highlighted sections on long pages
• Navigate directly to a highlight by clicking on its marker
• See which highlights are currently visible on screen

🌐 Multilingual Support
Available in both English and Korean — the UI adapts based on your browser’s language settings.

🧩 Popup Dashboard
Clicking the extension icon opens a popup with quick access to:

• Highlighted texts on the current page
• A toggle for the minimap
• Buttons to delete all highlights or export your data
• Navigation to a full-page manager for all highlights

💾 Local Storage & Full Privacy
All data — including highlights, colors, and page metadata — is stored locally in your browser using Chrome’s storage.local API. No data is ever transmitted outside your device, ensuring full privacy.
