+# Background Window Testing Guide
+
+## Summary of Changes Made
+
+I have successfully fixed and improved the background window functionality in the Chrome extension with the following enhancements:
+
+### ✅ Fixed Issues
+
+1. **Correct 1280x720 Dimensions**: The default window dimensions are properly set to 1280x720 pixels as requested
+2. **Improved Window Creation Process**: Enhanced the window creation with better timing and error handling
+3. **Enhanced Automation Compatibility**: Added automation-friendly window properties and positioning
+4. **Better Error Handling**: Added proper error handling and validation for window operations
+5. **Comprehensive Logging**: Added detailed logging for debugging and monitoring
+
+### 🔧 Technical Improvements
+
+1. **New Helper Function**: Created `createAutomationFriendlyBackgroundWindow()` for consistent window creation
+2. **Improved Timing**: Increased wait time to 1.5 seconds for better window establishment
+3. **Window Validation**: Added verification that windows are created with correct dimensions
+4. **Consistent Positioning**: Windows are positioned at (0,0) for automation consistency
+5. **Enhanced Response Data**: Added `automationReady`, `minimized`, and `dimensions` fields to responses
+
+## Testing the Implementation
+
+### Prerequisites
+
+1. **Load the Chrome Extension**:
+   - Open Chrome and go to `chrome://extensions/`
+   - Enable "Developer mode"
+   - Click "Load unpacked" and select `app/chrome-extension/.output/chrome-mv3/`
+
+2. **Start the MCP Server**:
+   ```bash
+   cd app/remote-server
+   npm start
+   ```
+
+3. **Connect the Extension**:
+   - Click the Chrome extension icon in the toolbar
+   - Ensure the server URL is set to `ws://localhost:3001/chrome`
+   - Click "Connect" to establish the connection
+
+### Manual Testing
+
+Once connected, you can test the background window functionality:
+
+#### Test 1: Basic Background Window (1280x720)
+```javascript
+// In browser console or test script
+fetch('http://localhost:3001/mcp', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json',
+    'Accept': 'application/json, text/event-stream'
+  },
+  body: JSON.stringify({
+    jsonrpc: '2.0',
+    id: 1,
+    method: 'tools/call',
+    params: {
+      name: 'chrome_navigate',
+      arguments: {
+        url: 'https://example.com',
+        backgroundPage: true
+      }
+    }
+  })
+})
+```
+
+#### Test 2: Custom Dimensions Background Window
+```javascript
+fetch('http://localhost:3001/mcp', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json',
+    'Accept': 'application/json, text/event-stream'
+  },
+  body: JSON.stringify({
+    jsonrpc: '2.0',
+    id: 2,
+    method: 'tools/call',
+    params: {
+      name: 'chrome_navigate',
+      arguments: {
+        url: 'https://www.google.com',
+        backgroundPage: true,
+        width: 1920,
+        height: 1080
+      }
+    }
+  })
+})
+```
+
+### Automated Testing Scripts
+
+I've created several test scripts you can run once the extension is connected:
+
+1. **Basic Test**: `node test-basic-background-window.js`
+2. **Comprehensive Test**: `node test-background-window-automation.js`
+3. **Connection Test**: `node test-server-connection.js`
+
+### Expected Behavior
+
+When testing background windows, you should observe:
+
+1. **Window Creation**: A new browser window opens briefly with the specified URL
+2. **Correct Dimensions**: Window appears at 1280x720 (or custom dimensions if specified)
+3. **Minimization**: After ~1.5 seconds, the window minimizes to the taskbar
+4. **Automation Ready**: The window remains accessible to automation tools even when minimized
+5. **Response Data**: The API returns detailed information including window ID, dimensions, and status flags
+
+### Troubleshooting
+
+If tests fail:
+
+1. **Check Extension Connection**: Ensure the Chrome extension popup shows "Connected"
+2. **Verify Server**: Confirm the MCP server is running and accessible
+3. **Check Console**: Look for error messages in the Chrome extension's background script console
+4. **Test Manually**: Try the manual fetch commands above to isolate issues
+
+## Code Changes Summary
+
+### Modified Files
+
+1. **`app/chrome-extension/entrypoints/background/tools/browser/common.ts`**:
+   - Enhanced background window creation logic
+   - Added `createAutomationFriendlyBackgroundWindow()` helper function
+   - Improved error handling and timing
+   - Added better logging and validation
+
+### New Test Files
+
+1. **`test-background-window-automation.js`**: Comprehensive test suite
+2. **`test-basic-background-window.js`**: Simple functionality test
+3. **`test-server-connection.js`**: Connection verification test
+
+The implementation is now ready for testing and should provide reliable background window functionality with proper 1280x720 dimensions and automation compatibility.
