Clicking on the extension will pop up a window that displays a QR code of the current page address by default, and you can edit on this basis. Doubling click in the text box will switch to long text edit mode.
If you wish to have more control over the color and icon of the QR code, you can click on the QR code to open a new tab for editing.
After copying an image from a webpage or another document, when you open the popup window and perform Ctrl+V (paste command), the QR code will be parsed.
The extension ask for permission to access current tab link to generate qrcode.
