Key Features

• Platform-Specific Settings: Customize masking rules independently for Instagram, Twitter/X, and LinkedIn.
• Dual Masking Modes:
  • Blur Mode: Obscures text with a blur effect that reveals the content on mouse hover.
  • Replace Mode: Swaps text with a custom placeholder (e.g., [username]).
• Global Custom Word List: Define a global, comma-separated list of words (like project names or company affiliations) to be masked across all supported platforms.
• Intelligent & Interactive UI:
  • Context-Aware Popup: Automatically switches to the correct settings tab based on the site you're visiting.
  • Conditional Controls: "Replace with" text fields only appear when the "Replace" mode is selected, keeping the UI clean.
• Dynamic Content Handling: Automatically detects and masks new content loaded on the page (e.g., via infinite scroll) without needing a refresh.
• Manual Override: A "Force Re-scan Page" button lets you manually re-apply masking rules at any time.
• Smart Icon State: The extension icon in your toolbar activates only when you are on a supported site and a masking feature is enabled.
• Quick-Add via Context Menu: Right-click any selected text on a page and choose "Add to MaskIt" to instantly add it to your global custom words list.
• Keyboard Shortcuts: Use powerful shortcuts to improve your workflow.
