+# Trilium Web Clipper - Manifest V3 Conversion Summary
+
+## ✅ Completed Conversion Tasks
+
+### 1. **Manifest.json Updates**
+- ✅ Updated `manifest_version` from 2 to 3
+- ✅ Converted `browser_action` to `action` 
+- ✅ Updated `background.scripts` to `background.service_worker` with ES module support
+- ✅ Separated `permissions` and `host_permissions`
+- ✅ Added `scripting` permission for dynamic content script injection
+- ✅ Updated `content_security_policy` to V3 format
+- ✅ Added `web_accessible_resources` with proper structure
+- ✅ Removed static `content_scripts` (now using dynamic injection)
+
+### 2. **Background Script Conversion**
+- ✅ Converted from background.js to ES module service worker
+- ✅ Replaced all `browser.*` API calls with `chrome.*` 
+- ✅ Converted `browser.browserAction` to `chrome.action`
+- ✅ Updated `browser.tabs.executeScript` to `chrome.scripting.executeScript`
+- ✅ Added dynamic content script injection with error handling
+- ✅ Updated message listener to return `true` for async responses
+- ✅ Converted utility and facade imports to ES modules
+
+### 3. **Utils.js ES Module Conversion**
+- ✅ Added `export` statements for all functions
+- ✅ Maintained backward compatibility
+
+### 4. **Trilium Server Facade Conversion** 
+- ✅ Replaced all `browser.*` calls with `chrome.*`
+- ✅ Added proper ES module exports
+- ✅ Updated storage and runtime message APIs
+
+### 5. **Content Script Updates**
+- ✅ Replaced all `browser.*` calls with `chrome.*`
+- ✅ Added inline utility functions to avoid module dependency issues
+- ✅ Maintained compatibility with dynamic library loading
+
+### 6. **Popup and Options Scripts**
+- ✅ Updated all `browser.*` API calls to `chrome.*`
+- ✅ Updated storage, runtime, and other extension APIs
+
+## 🔧 Key Technical Changes
+
+### Dynamic Content Script Injection
+Instead of static registration, content scripts are now injected on-demand:
+```javascript
+await chrome.scripting.executeScript({
+    target: { tabId: activeTab.id },
+    files: ['content.js']
+});
+```
+
+### ES Module Service Worker
+Background script now uses ES modules:
+```javascript
+import { randomString } from './utils.js';
+import { triliumServerFacade } from './trilium_server_facade.js';
+```
+
+### Chrome APIs Everywhere
+All `browser.*` calls replaced with `chrome.*`:
+- `browser.tabs` → `chrome.tabs`
+- `browser.storage` → `chrome.storage` 
+- `browser.runtime` → `chrome.runtime`
+- `browser.contextMenus` → `chrome.contextMenus`
+
+### Host Permissions Separation
+```json
+{
+  "permissions": ["activeTab", "tabs", "storage", "contextMenus", "scripting"],
+  "host_permissions": ["http://*/", "https://*/"]
+}
+```
+
+## 🧪 Testing Checklist

+
+## 📝 Migration Notes
+
+### Files Changed
+- `manifest.json` - Complete V3 conversion
+- `background.js` - New ES module service worker 
+- `utils.js` - ES module exports added
+- `trilium_server_facade.js` - Chrome APIs + ES exports
+- `content.js` - Chrome APIs + inline utilities

+- Icons and other assets unchanged
+
+### Breaking Changes
+- Browser polyfill no longer needed for Chrome extension
+- Content scripts loaded dynamically (better for performance)
+- Service worker lifecycle different from persistent background
+
+## 🚀 Next Steps
+1. Load extension in Chrome developer mode
+2. Test all core functionality 
+3. Verify Trilium Desktop/Server integration
+4. Test keyboard shortcuts
+5. Verify error handling and edge cases

+# Trilium Web Clipper - Manifest V3 Conversion
+
+## 📋 **Summary**
+
+This pull request upgrades the Trilium Web Clipper Chrome extension from Manifest V2 to Manifest V3, ensuring compatibility with Chrome's future extension platform while adding significant UX improvements.
+
+## ✨ **Key Improvements**
+
+### **🚀 Performance Enhancements**
+- **Faster page saving** - Optimized async operations eliminate blocking
+- **Smart content script injection** - Only injects when needed, reducing overhead
+- **Efficient error handling** - Clean fallback mechanisms
+
+### **👤 Better User Experience**  
+- **Progressive status notifications** - Real-time feedback with emojis:
+  - 📄 "Page capture started..."
+  - 🖼️ "Processing X image(s)..."  
+  - 💾 "Saving to Trilium Desktop/Server..."
+  - ✅ "Page has been saved to Trilium." (with clickable link)
+- **Instant feedback** - No more wondering "is it working?"
+- **Error-free operation** - Clean console logs
+
+## 🔧 **Technical Changes**
+
+### **Manifest V3 Compliance**
