v1.0.0 - Initial Release: Base64 Auto Decoder

🎉 Welcome to Base64 Auto Decoder (v1.0.0)

Base64 Auto Decoder is a lightweight, zero-dependency Chrome extension (Manifest V3) that automatically detects, decodes, and replaces Base64 strings on webpages with readable text and a one-click copy button.

No more selecting text, opening context menus, or pasting into external decoder tools!

✨ Key Features

• ⚡ Automatic Detection & In-Place Replacement: Scans visible text nodes upon page load and dynamically handles SPA content (via MutationObserver).
• 🛡️ Smart Anti-False-Positive Engine:
  • Full UTF-8 support for Chinese, Japanese, Korean, emojis, and special characters.
  • Intelligent filtering to prevent false positives on normal English words, Git commit hashes, UUIDs, and pure numbers.
• 📋 One-Click Copy: A discreet copy icon (📋) appears next to the decoded text with instant visual feedback (Copied!).
• 🔍 View Original on Hover: Hover over any decoded text to see the original Base64 string in a tooltip.
• 🎛️ Minimalist ON/OFF Toggle: Clean popup interface with an iOS-style toggle. Turning it off instantly restores original strings on the page.
• 🌐 Built-in i18n: Native support for both English and Simplified Chinese (zh_CN).
• 🔒 100% Privacy-First: Completely runs offline in your browser. Zero tracking, zero data collection.
