Browser Extension Health Check Helper is a small utility for everyday users. It helps you quickly see which extensions are installed in your browser, what powerful permissions each one has, and provides an easy-to-understand risk level with clear action suggestions. The goal is not to scare you, but to make it obvious at a glance: Which extensions have very powerful permissions and deserve extra attention. Which extensions are medium-risk and are better used with caution or limited usage. Which extensions are relatively low-risk and generally safe to keep. Main features 🧪 One-click health check for installed extensions Automatically reads all installed items of type extension in your browser and generates a health-check list. 🔐 Risk evaluation based on permissions and install type Combines key permissions (such as accessing all websites, reading/modifying cookies, intercepting network requests, viewing browsing history, etc.) with the install source (normal install / developer mode / side-loaded, etc.) to rate each extension from low to critical risk. 🎯 Highlighted key risk factors For high-risk and critical-risk extensions, the tool additionally lists “key risk factors”, for example: Access to all website content Intercepting and modifying network requests Reading and modifying browsing history / cookies Installed via developer mode or side-loading ✅ Actionable suggestions Provides plain-language guidance based on the risk level, such as: Safe to keep, but recommended to review from time to time. If not essential, consider a lighter alternative with fewer permissions. Strongly recommended to remove to reduce the chance of tracking or data theft. 🌏 Multi-language interface Supports Chinese, English, Japanese, French and Russian. You can switch languages from the dropdown in the top-right corner. 🎨 Multiple themes and quick rescan Offers several visual themes (dark, blue glow, neon, sunset, cyber green, etc.) and a “Rescan” button, so you can quickly re-run the health check after installing or removing extensions. *********************************************** 浏览器插件健康体检小助手，是一款面向普通用户的小工具，帮你快速看懂自己浏览器里安装了哪些扩展、各自拥有哪些关键权限，并给出简单直观的风险等级和操作建议。 工具的目标不是吓唬人，而是让你一眼看出： 1、哪些扩展权限非常大、需要重点关注； 2、哪些扩展属于中等风险，适合“观望＋限制使用”； 3、哪些扩展整体风险较低，可以放心保留。 主要功能 🧪 一键体检已安装扩展 自动读取当前浏览器中类型为 extension 的扩展，生成体检列表。 🔐 基于权限和安装方式的风险评估 结合扩展的关键权限（访问所有网站、读取/修改 Cookie、拦截网络请求、查看浏览记录等）和安装来源（正常安装 / 开发者模式 / 旁加载等），给出从低风险到极高风险的评分和标签。 🎯 重点风险提示 对高风险和极高风险扩展，额外列出“重点关注点”，例如： 访问所有网站内容 拦截和修改网络请求 读取和修改浏览记录 / Cookie 来自开发者模式或旁加载 ✅ 操作建议文案 根据风险等级给出通俗易懂的建议，例如： 可以保留，但建议定期检查； 如非刚需工具，建议寻找权限更小的替代； 强烈建议卸载，以免被用于跟踪或窃取隐私。 🌏 多语言界面 支持中文、英文、日文、法文、俄文，可在界面右上角一键切换。 🎨 多种主题与重新体检 提供深色、蓝色渐变、霓虹、日落、Cyber Green 等多种背景主题，并支持「再体检一次」按钮，方便你在安装/卸载扩展后重新查看最新结果。
