NotesQR Browser Extension: Quick Access to File Sharing

The NotesQR browser extension brings the power of instant file sharing directly to your browser toolbar. This comprehensive guide will show you how to install it, use it effectively, and get the most out of this convenient tool.

Why Use the Extension?

Convenience

The extension provides several convenience benefits:

One-Click Access:

Instead of typing the URL or bookmarking the website, you can access NotesQR with a single click from your browser toolbar. This saves time and makes file sharing a seamless part of your workflow.

Always Available:

The extension is always accessible from any webpage. Whether you're reading an article, working on a document, or browsing social media, you can quickly share files without leaving your current page.

Quick Sharing:

Share files without navigating away from what you're doing. The extension opens in a popup, allowing you to share files and return to your work immediately.

Speed

The extension offers several speed advantages:

Faster Workflow:

No need to navigate to the website—the extension is always one click away. This eliminates the time spent loading the main website and navigating to the file sharing interface.

Persistent Sessions:

The extension can maintain connection state between uses, making it faster to start new file sharing sessions. While the web version requires establishing a new session each time, the extension can remember your preferences.

Quick File Selection:

The extension provides the same drag-and-drop interface as the web version, but with the added convenience of being accessible from anywhere in your browser.

Integration

Browser Integration:

The extension integrates with your browser's native features, providing a more seamless experience than using the web version.

Notification Support:

Some browsers allow extensions to show notifications, which can be useful for transfer status updates (future feature).

Context Menu Integration:

Future versions may include right-click context menu options for sharing files directly from web pages.

Installation

Chrome/Chromium Browsers

Installing the NotesQR extension in Chrome or Chromium-based browsers (like Edge, Brave, or Opera) is straightforward:

Visit the Chrome Web Store: Go to the NotesQR extension page on the Chrome Web Store.
Click "Add to Chrome": You'll see a prominent "Add to Chrome" button on the extension page.
Confirm the installation: Chrome will show a confirmation dialog asking you to confirm the installation. Review the permissions requested and click "Add extension" if you're comfortable with them.
Verify installation: After installation, you should see the NotesQR icon in your browser toolbar. If you don't see it, you may need to click the puzzle piece icon (extensions menu) and pin the NotesQR extension.

Permissions Explained:

The extension may request the following permissions:

WebRTC access: Required for peer-to-peer file transfers
Storage: For caching connection data and preferences
Active tab: For some browser integration features

These permissions are necessary for the extension to function properly and are standard for file-sharing extensions.

Firefox

Installing the NotesQR extension in Firefox follows a similar process:

Visit Firefox Add-ons: Go to the NotesQR extension page on Firefox Add-ons.
Click "Add to Firefox": Click the prominent "Add to Firefox" button.
Confirm the installation: Firefox will show a confirmation dialog. Review the permissions and click "Add" if you're comfortable.
Verify installation: The NotesQR icon should appear in your Firefox toolbar. If not, you may need to customize your toolbar to show it.

Firefox-Specific Notes:

Firefox has slightly different permission handling than Chrome, but the functionality is the same. The extension works identically in both browsers.

Using the Extension

Opening NotesQR

Using the extension is simple:

Click the NotesQR icon: Look for the NotesQR icon in your browser toolbar. It should be visible after installation.
The popup opens: Clicking the icon opens a popup window with the NotesQR interface. This popup contains all the functionality of the web version.
You're ready to share: The interface is identical to the web version, so if you've used NotesQR before, you'll feel right at home.

Popup Behavior:

The popup opens in a small window that overlays your current page
You can move the popup around if needed (depending on browser)
Closing the popup doesn't interrupt active transfers
The popup can be resized in some browsers

Sharing Files

The extension works exactly like the web version:

Select files: Click "Select Files" or drag and drop files into the upload area. The interface is the same as the web version.

Share: Send the QR code or link to your recipient using any method you prefer—email, messaging apps, or in person.
Transfer: Files transfer directly peer-to-peer, exactly as they do in the web version. The extension doesn't change how transfers work.

File Selection Tips:

Drag and drop works the same as the web version

Chrome: Go to chrome://extensions/, find NotesQR, and click "Details" to manage permissions
