# Browser Extension Permissions
This document explains the permissions requested by the DocuElevate browser extension.
## Requested Permissions
The extension requests the following permissions in `manifest.json`:
### activeTab
- **Purpose**: Get the URL of the currently active tab
- **Usage**: When you click the extension icon, it reads the current tab's URL to display in the popup
- **Privacy**: Only accesses the active tab when you explicitly open the popup
- **Alternative**: Without this, the extension couldn't show you which file you're sending
### storage
- **Purpose**: Save your configuration (server URL and session cookie)
- **Usage**: Stores your DocuElevate server URL and optional session cookie locally
- **Privacy**: All data stays on your device; nothing is sent to third parties
- **Alternative**: Without this, you'd need to reconfigure the extension every time
### contextMenus
- **Purpose**: Add "Send to DocuElevate" to the right-click menu
- **Usage**: Creates a context menu item for quick access
- **Privacy**: No data access; only adds a menu item
- **Alternative**: Without this, you'd only have the toolbar icon
### notifications
- **Purpose**: Show success/error notifications
- **Usage**: Displays browser notifications when files are sent successfully or errors occur
- **Privacy**: Only shows notifications based on your actions
- **Alternative**: Without this, you wouldn't get feedback from context menu actions
## No Host Permissions
The extension has an **empty `host_permissions` array** (`[]`).
### Why Empty?
- **Privacy-First**: The extension doesn't request blanket access to all websites
- **User-Controlled**: You configure the DocuElevate server URL, not us
- **Minimal Permissions**: Only accesses the server you explicitly configure
- **Dynamic Access**: API requests are made from popup/background scripts, not from web pages
### How It Works
1. You configure your DocuElevate server URL in the extension
2. The extension stores this URL in local storage
3. When you send a file, the extension makes a direct API request to your configured server
4. No need for static host permissions because the extension doesn't inject scripts or modify web pages
### Comparison to Other Extensions
Many similar extensions request:
-`"<all_urls>"` or `"*://*/*"` - Access to all websites
-`"http://*/*"` and `"https://*/*"` - Access to all HTTP/HTTPS sites
DocuElevate requests:
-`[]` - No blanket host permissions
- ✅ Only access to your configured server (via fetch API)
## Permission Justification
| Permission | Required? | Justification |
|------------|-----------|---------------|
| activeTab | ✅ Yes | Must read current tab URL to send files |
| storage | ✅ Yes | Must save configuration to function |
| contextMenus | ⚠️ Optional | Nice to have for quick access |
| notifications | ⚠️ Optional | Nice to have for feedback |
## Security Benefits
1. **No Web Page Access**: Extension can't read or modify content on websites you visit
2. **No Browsing History**: Extension doesn't track your browsing
3. **No Cross-Site Access**: Extension only talks to your configured server
4. **User-Controlled**: All communication is initiated by you
5. **Transparent**: All code is visible in the extension folder
## How to Verify Permissions
### Chrome/Edge
1. Go to `chrome://extensions/` or `edge://extensions/`
2. Find "DocuElevate - Send to Document Processor"
3. Click "Details"
4. Review "Permissions" section
### Firefox
1. Go to `about:addons`
2. Find "DocuElevate - Send to Document Processor"
3. Click on the extension name
4. View "Permissions" tab
## Reducing Permissions Further
If you want even fewer permissions:
1. **Remove contextMenus**: Delete the `contextMenus` permission from `manifest.json`
- Trade-off: Lose right-click menu option
- You'd only have the toolbar icon
2. **Remove notifications**: Delete the `notifications` permission
- Trade-off: No success/error notifications
- You'd only see status in the popup
3. **Remove content script**: Delete the `content_scripts` section
- Trade-off: None (it's not actively used currently)
- Reduces extension footprint slightly
## Privacy Statement
The DocuElevate browser extension:
- ✅ Does NOT collect any personal data
- ✅ Does NOT track your browsing history
- ✅ Does NOT send data to third parties
- ✅ Does NOT modify web page content
- ✅ Does NOT inject ads or tracking scripts
- ✅ Only communicates with YOUR configured DocuElevate server
- ✅ Stores configuration locally on your device only
## Questions?
If you have concerns about permissions or privacy, please:
- Review the source code in the `browser-extension` folder
- Open an issue on [GitHub](https://github.com/christianlouis/DocuElevate/issues)
- Check the [Browser Extension Guide](../docs/BrowserExtension.md)

- Do not include trailing slashes or API paths
- The extension will automatically append `/api/process-url`
### Session Cookie (Optional)
If your DocuElevate instance has authentication enabled, you need to provide a session cookie:
1. **Get Your Session Cookie**:
- Log in to DocuElevate in your browser
- Open browser DevTools (F12)
- Go to the "Application" or "Storage" tab
- Find "Cookies" in the left sidebar
- Look for a cookie named `session`
- Copy its value
2. **Enter in Extension**:
- Format: `session=your_session_value_here`
- The extension will include this in API requests
**Security Note**: Your session cookie is stored securely in the browser's extension storage. Never share your session cookie with others.
## Supported File Types
The extension can send any URL, but DocuElevate will only process supported file types:
- **Documents**: PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX, TXT, CSV, RTF
- **Images**: JPG, PNG, GIF, BMP, TIFF, WebP, SVG
## Troubleshooting
### "Failed to connect to DocuElevate server"
**Cause**: The extension cannot reach your DocuElevate server.
**Solutions**:
- Verify your server URL is correct
- Check that your DocuElevate server is running
- Ensure there are no firewall or CORS issues
- Try accessing the API directly: `https://your-server.com/api/process-url`
### "Authentication required" or 401 Error
**Cause**: Your DocuElevate instance requires authentication.
**Solutions**:
- Get your session cookie (see Configuration section)
- Enter the session cookie in the extension settings
- Ensure your session hasn't expired (log in again if needed)
### "Unsupported file type"
**Cause**: The URL doesn't point to a supported file type.
**Solution**:
- Verify the URL ends with a supported file extension
- Check that the Content-Type header is set correctly by the server
### "File too large"
**Cause**: The file exceeds the maximum upload size configured in DocuElevate.
**Solutions**:
- Check your DocuElevate `MAX_UPLOAD_SIZE` configuration
- Try a smaller file
- Contact your DocuElevate administrator to increase the limit
## Privacy & Security
### Permissions Explained
The extension requests minimal permissions:
- **activeTab**: To get the URL of the current tab
- **storage**: To save your server URL and session cookie configuration
- **contextMenus**: To add the "Send to DocuElevate" option to right-click menus
- **notifications**: To show success/error notifications
### Data Handling
- **No Data Collection**: The extension does not collect, store, or transmit any data except what you explicitly send to your DocuElevate server
- **Local Configuration**: Your server URL and session cookie are stored locally in your browser
- **Direct Communication**: All API requests go directly from your browser to your DocuElevate server
- **No Third Parties**: No data is sent to third-party services
## Development
### Building from Source
The extension is already in a usable state in the `browser-extension` folder. No build process is required.
### File Structure

### Testing
1. Load the extension in developer mode
2. Configure it with your local DocuElevate instance
3. Test with various file URLs
4. Check the browser console for any errors
5. Verify files are being processed in DocuElevate

# Browser Extension Guide
The DocuElevate Browser Extension enables users to send files from their web browser directly to DocuElevate for processing.
## Overview
The browser extension provides a seamless way to process files without manually downloading them first. Users can send file URLs with a single click, and DocuElevate will download and process the files automatically.
## Features
### Core Functionality
- **One-Click File Sending**: Send file URLs from the browser to DocuElevate
- **Context Menu Integration**: Right-click on links or pages to send them
- **Popup Interface**: Simple configuration and file submission UI
- **Status Notifications**: Immediate feedback on submission success or failure
### Security Features
- **Minimal Permissions**: Only requests necessary browser permissions
- **Secure Storage**: Configuration stored locally in browser extension storage
- **Direct Communication**: All requests go directly to your DocuElevate server
- **Session-Based Auth**: Supports DocuElevate authentication via session cookies
### Cross-Browser Support
The extension is compatible with:
- Google Chrome
- Microsoft Edge
- Chromium-based browsers (Brave, Opera, etc.)
- Mozilla Firefox (with minor adjustments)
## Installation
### For End Users
See the [Browser Extension README](../browser-extension/README.md) for detailed installation instructions.
Quick steps:
1. Load the extension from the `browser-extension` folder
2. Configure your DocuElevate server URL
3. Optionally add authentication (session cookie)
4. Start sending files!
### For Administrators
#### Prerequisites
- DocuElevate server running with URL upload API enabled
- Server accessible from users' browsers (not blocked by firewall/CORS)
- Optional: Authentication configured if required
#### Deployment Options
**Option 1: Direct Distribution**
- Share the `browser-extension` folder with users
- Users load it as an unpacked extension
**Option 2: Internal Extension Store**
- Package the extension as a .zip file
- Distribute via internal Chrome Web Store or Firefox Add-ons for Enterprise
**Option 3: Public Store** (requires additional steps)
- Submit to Chrome Web Store
- Submit to Firefox Add-ons
## Configuration
### Extension Settings
Users need to configure two settings:
1. **DocuElevate Server URL** (required)
- Format: `https://docuelevate.example.com`
- Must be accessible from user's browser
- Should not include trailing slashes or API paths
2. **Session Cookie** (optional, if auth enabled)
- Format: `session=cookie_value_here`
- Obtained by logging into DocuElevate and copying session cookie
- Expires when the session expires (users need to update it)
### Server Configuration
No server-side configuration is required. The extension uses the existing URL upload API endpoint:
```
POST /api/process-url
```
Ensure this endpoint is:
- Accessible from users' browsers
- Not blocked by CORS policies (if different domain)
- Properly secured with authentication if needed
## Usage
### Sending Files via Popup
1. Click the DocuElevate extension icon
2. The current page URL is displayed
3. Optionally enter a custom filename
4. Click "Send to DocuElevate"
5. Status message shows success or error
### Sending Files via Context Menu
1. Right-click on any link or the current page
2. Select "Send to DocuElevate"
3. A notification appears with the result
### Supported URLs
The extension can send any URL, but DocuElevate will only process:
**Document URLs**:
- PDFs: `https://example.com/document.pdf`
- Office: `https://example.com/report.docx`
- Spreadsheets: `https://example.com/data.xlsx`
- Text files: `https://example.com/notes.txt`
**Image URLs**:
- `https://example.com/image.jpg`
- `https://example.com/scan.png`
- `https://example.com/diagram.svg`
## How It Works
### Architecture
```
┌─────────────┐ ┌──────────────────┐ ┌──────────────┐
│ Browser │ │ Browser Ext. │ │ DocuElevate │
│ Tab │────────▶│ (popup.js) │────────▶│ Server │
│ │ URL │ │ API │ │
└─────────────┘ └──────────────────┘ Request └──────────────┘
│ Stores config in
┌──────────────────┐
│ Browser Storage │
│ (chrome.storage) │
└──────────────────┘
```
### Data Flow
1. **User initiates send**: Via popup or context menu
2. **Extension gets current URL**: From active tab
3. **Extension loads config**: Server URL and session cookie from storage
4. **API request sent**: POST to `/api/process-url` with URL and optional filename
5. **DocuElevate processes**:
- Downloads file from URL
- Validates file type and size
- Enqueues for processing (OCR, metadata extraction)
6. **Response returned**: Task ID and status
7. **User notified**: Success or error message displayed
### Security Flow
The extension implements several security measures:
1. **No direct file access**: Extension only sends URLs, not file contents
2. **User-controlled config**: Server URL and auth stored per-user
3. **HTTPS recommended**: Encourages secure communication
4. **Minimal permissions**: Only requests necessary browser APIs
5. **Server-side validation**: DocuElevate validates all URLs (SSRF protection)
## Technical Details
### Extension Structure
**manifest.json**: Extension metadata and configuration
- Manifest v3 format (latest standard)
- Minimal permissions requested
- Compatible with Chrome, Edge, and Firefox
**popup/**: User interface files
- `popup.html`: Extension popup interface
- `popup.css`: Styling with modern UI design
- `popup.js`: Configuration and file sending logic
**scripts/**: Background functionality
- `background.js`: Service worker for context menu and notifications
- `content.js`: Content script for page interaction (minimal)
**icons/**: Extension icons in multiple sizes
### API Integration
The extension communicates with DocuElevate via the URL upload API:
**Request Format**:
```javascript
POST /api/process-url
Content-Type: application/json
Cookie: session=<session_value> // if auth enabled
{
"url": "https://example.com/file.pdf",
"filename": "optional-custom-name.pdf" // optional
}
```
**Response Format**:
```javascript
{
"task_id": "abc-123-def",
"status": "queued",
"message": "File downloaded from URL and queued for processing",
"filename": "file.pdf",
"size": 1024
}
```
**Error Response**:
```javascript
{
"detail": "Error message explaining what went wrong"
}
```
### Browser Permissions
The extension requests these permissions:
- **activeTab**: Get URL of current tab
- **storage**: Save configuration (server URL, session cookie)
- **contextMenus**: Add "Send to DocuElevate" to right-click menu
- **notifications**: Show success/error notifications
All permissions are used only for stated purposes. No data is collected or transmitted to third parties.
## Troubleshooting
### Common Issues
**"Failed to connect to DocuElevate server"**
- Check server URL is correct and accessible
- Verify server is running
- Check firewall/network settings
- Test API directly: `curl https://your-server/api/process-url`
**"Authentication required" (401 error)**
- User needs to add session cookie
- Session may have expired (log in again)
- Check AUTH_ENABLED setting in DocuElevate
**"Unsupported file type" (400 error)**
- URL must point to a supported file type
- Check file extension and Content-Type header
- See DocuElevate supported file types
**"File too large" (413 error)**
- File exceeds MAX_UPLOAD_SIZE setting
- Contact admin to increase limit or use smaller file
**Extension not appearing**
- Ensure developer mode is enabled
- Reload the extension
- Check browser console for errors
### Debug Mode
To debug the extension:
1. **Open Extension Console**:
- Chrome: Right-click extension icon → "Inspect popup"
- Or go to `chrome://extensions/` → Click "Inspect views: service worker"
2. **Check Console Logs**:
- Look for error messages
- Verify API requests are being sent
- Check response status codes
3. **Test API Directly**:
```bash
curl -X POST https://your-server/api/process-url \
-H "Content-Type: application/json" \
-H "Cookie: session=your_session" \
-d '{"url": "https://example.com/test.pdf"}'
```
## Best Practices
### For Users
- Keep your session cookie secure and don't share it
- Verify the DocuElevate server URL is correct before saving
- Only send files from trusted sources
- Check file size limits before sending large files
### For Administrators
- Configure HTTPS for production servers
- Set appropriate MAX_UPLOAD_SIZE limits
- Enable authentication for security
- Monitor API usage and set rate limits if needed
- Provide clear documentation to users on getting session cookies
## Future Enhancements
Possible future improvements:
- **OAuth2 authentication** instead of session cookies
- Current session cookie approach has limitations:
- Session cookies expire and need manual refresh
- Users must manually copy cookie from browser DevTools
- No automatic token refresh mechanism
- OAuth2 would provide:
- Automatic token refresh
- Better security with short-lived access tokens
- Easier user experience (login flow instead of cookie copying)
- File preview before sending
- Batch processing multiple URLs
- Progress indication for large files
- History of sent files
- Custom processing options (OCR language, metadata fields, etc.)
### Session Cookie Security Best Practices
For users of the current implementation:
1. **Keep session cookies secure**: Never share your session cookie value
2. **Refresh regularly**: Session cookies expire; update the extension when you log in again
3. **Use HTTPS**: Always use HTTPS for your DocuElevate server
4. **Clear on logout**: Remove the session cookie from extension when logging out
5. **Private browsing**: Session cookies from private/incognito windows have shorter lifetimes
