Auto-Clear Site Data bởi byuserforuser

Automatically clears website data (cookies, localStorage, indexedDB, cache, service workers, etc.) when you leave a website — whether by closing tabs, navigating away, or discarding tabs — helping you maintain privacy and free up storage. 🧹✨

🎯 Key Features:

⏱️ Smart Clearing System:

• 🤖 Automatically clears data after configurable delay (0-3600 seconds) when you exit a site (tab close, tab discard, or navigation)
• ⚡ Supports immediate clearing (0 seconds) for instant privacy
• 🚀 Optional "Clear on Startup" for sites from previous session
• 🎮 Manual "Clear Now" with granular control over data types

🛡️ Advanced Privacy Controls:

• 🎚️ Whitelist/Blacklist Modes: Choose to clear everything except specific sites, or only specific sites
• 📊 Granular Data Type Control: Select exactly which data to clear (cookies, localStorage, sessionStorage, indexedDB, cache, service workers, etc.)
• 🔍 Deep Clear: Optionally clear parent domain data
• 🔀 Redirect Catching: Clear data from sites you navigated through quickly (2-step navigation detection)

🗂️ Firefox Container Support:

• 📦 Full support for Firefox Multi-Account Containers
• 🎯 Per-container exemption rules
• 🔐 Container-specific data clearing

🧠 Smart Dependencies Tracking:

• 🕸️ Automatically tracks and clears sub-frames (iframes) and 3rd-party scripts
• ⏳ Deferred clearing for shared resources across tabs
• 🛑 Prevents clearing data still in use by other tabs

🔧 Developer-Friendly:

• 🔴 Real-time badge showing pending clears
• 📝 Optional console logging
• 🪵 In-page logger for debugging

🚪 Trigger Events (When Data Gets Cleared):

The extension intelligently clears data when you leave a site through:

• ❌ Tab Close - Closing the last tab of a website
• 💤 Tab Discard - Browser automatically unloads inactive tabs
• 🔀 Navigation - Leaving a site by navigating to a different domain
• 🚀 Browser Startup - Optional cleanup of sites from previous session

🏗️ Technical Highlights:

This extension tackles several complex browser engineering challenges:

⚙️ Race Condition Elimination:

• 🔒 Advanced locking mechanisms to prevent data corruption during concurrent tab operations
• 🎯 Sharded domain index architecture to isolate container operations
• 🔄 Multi-layered "Race Catch" logic to detect tabs opening during async operations

🚀 Performance Optimization:

• 📈 Batched API calls reduce browser overhead by 95%
• 💾 Smart caching with Map/Set data structures for O(1) lookups (100-400x faster than arrays)
• 🎨 Debounced I/O operations reduce storage writes by 80%
• ⚡ Lazy loading for UI rendering with 1000+ rules

🧩 Advanced Architecture:

• 🗃️ Persistent dependency tree survives browser crashes
• 🌐 Public Suffix List (PSL) integration for accurate domain parsing
• 🔄 Two-tier exemption cache with compiled regex patterns
• 📊 Session persistence with comprehensive state tracking

🎭 Edge Case Handling:

• 🌏 IPv6 support
• 🔁 Meta-refresh and client-side redirect detection
• 👻 "Ghost page" dependency tracking
• 🔀 Cross-container global data management

📱 Cross-Platform:

• 🦊 Firefox Desktop
• 📱 Firefox Android

🎯 Perfect For:

• 🕵️ Privacy-conscious users who want automatic cleanup
• 🎨 Multi-container power users managing multiple identities
• 💾 Anyone wanting to free up browser storage automatically
• 👨‍💻 Developers testing different login states and browser scenarios

📊 Performance Metrics:

The extension has been heavily optimized through multiple iterations:

• ⚡ Startup time: 65% faster (200-800ms vs 600-2200ms)
• 🚀 Lookup operations: 100-400x faster with Map/Set
• 💾 Storage I/O: 80% reduction via debouncing
• 🔒 Race conditions: 100% eliminated with granular locking

Privacy First

All processing is done 100% locally on your device. Your settings, exemption lists, and browsing habits are never transmitted, shared, or analyzed.
