Excellent and super fast. The tool i used previously took several seconds to generate the code. This one does it immediately when i hit the button.

It does what it says without any unnecessary extras. Unlike most other add-ons, it doesn't require any unnecessary permissions.
The only minor issue is that the black icon on my dark-themed toolbar is barely visible. It would be perfect if you could add a light background.

I don't understand the bad reviews: the extension works fine and doesn't add tracking junk to the qr codes it generate.

Works perfectly!
No complaints from me. :)
