🚫 ForgetMeNot - Website Oblivion Assistant

中文版

ForgetMeNot is a privacy-focused Chrome extension. Its core function is simple yet powerful: Automatically clear all browsing data (Cookies, Cache, LocalStorage, etc.) for a website when you close its last remaining tab.

Prevent unwanted websites from tracking your digital footprint and keep your browser lightweight and private.

✨ Key Features

• Auto-Cleanup: Monitors tab status and triggers cleanup only when the "last tab" of a specific domain is closed, ensuring no interference with your active browsing sessions.
• Dual Modes:
  • ⛔ Blacklist Mode (Default): Only websites listed will have their data cleared upon closing.
  • 🛡️ Whitelist Mode: Websites listed are "kept/preserved," while all other unlisted websites are cleared when their tabs are closed.
• Powerful Rule System: Supports Regular Expressions (Regex), allowing you to flexibly match domains (e.g., matching all subdomains).
• Modern Architecture: Built on Chrome Manifest V3 using Service Workers for better performance and enhanced security.
• Beautiful Interface: Clean settings page with aesthetic pink-themed success notifications.

Mode Descriptions

• Blacklist: Ideal for users who only want to target specific websites (e.g., news sites, social media) for cleanup.
• Whitelist: Designed for privacy enthusiasts. You can whitelist essential sites (e.g., Email, internal company systems), and data for all other randomly browsed sites will be cleared automatically.

storage	Used to save your Blacklist/Whitelist configurations.
host_permissions	Requires <all_urls> so the background script can read the source URL of closed tabs for domain matching.
