To create the CanvasShield extension:

# Create extension directory and copy required files mkdir -p ~/Desktop/CanvasShieldExt cp -r ~/Documents/Spring2025/InformationSystemsAndComputerSecurity/CanvasShield/{manifest.json,popup,scripts,assets,lib} ~/Desktop/CanvasShieldExt/

Then load the unpacked extension in your browser's extension management page. For custom configurations, modify the manifest.json file to adjust permissions, background scripts, or extension metadata.
