|
|
|
|
### Features Implemented
|
|
|
|
1. **Popup Interface**
|
|
- Configuration screen for server URL and auth
|
|
- File sending interface with current URL display
|
|
- Optional filename input
|
|
- Status messages (success/error/info)
|
|
- Settings management
|
|
|
|
2. **Context Menu Integration**
|
|
- Right-click on links to send directly
|
|
- Right-click on current page to send
|
|
- Browser notifications for feedback
|
|
|
|
3. **Configuration Storage**
|
|
- Secure storage in browser extension storage
|
|
- Server URL configuration
|
|
- Optional session cookie for authentication
|
|
- Persistent across browser sessions
|
|
|
|
4. **API Integration**
|
|
- Uses existing `/api/process-url` endpoint
|
|
- SSRF protection (server-side)
|
|
- File type validation (server-side)
|
|
- File size limits (server-side)
|
|
- Proper error handling
|
|
|
|
5. **Security Features**
|
|
- Minimal permissions (4 permissions, no host access)
|
|
- No data collection
|
|
- No third-party communication
|
|
- User-controlled configuration
|
|
- Direct server communication only
|
|
|
|
### Permissions (Minimal)
|
|
|
|
```json
|
|
"permissions": [
|
|
"activeTab", // Get current tab URL
|
|
"storage", // Save configuration
|
|
"contextMenus", // Add right-click menu
|
|
"notifications" // Show success/error alerts
|
|
],
|
|
"host_permissions": [] // No blanket website access!
|
|
```
|
|
|
|
**Privacy-First Approach:**
|
|
- Empty `host_permissions` array (no blanket access to websites)
|
|
- Only communicates with user-configured server
|
|
- No tracking or analytics
|
|
- All data stored locally
