I use this Extension frequently on FireFox. When I want to view a website on my phone or give the exact qr link to someone I use this. It also comes in handy when making flyers and other things which requires a phone to be used on.
The requests for plugin and such do seem to be moving past what I would consider “core” functionality for a browser. Perhaps time to start opening things up to third-party plugins?
Other than that, total +1 for QR code-ing the current URL in Brave
1 up for adding this Extension - very useful to be able to scan a QR code from the desktop browser to share the address on mobile - I use it all the time in firefox, or jump to firefox to use it.
