Firefox Add-ons website no longer provides OpenSearch since Feb 2020, since then, this WebExtension is written as revival of an OpenSearch tool that generate QR codes using online web service, as it's source code is still available at
GitHub.
This extension uses an online QR code generator service, sends the text searched to the API site and returns a picture of the QR code representing the text. This is useful as a simple alternative to copy-paste text between a desktop PC and a mobile device.
Don't use this tool to convert passwords or other sensible data, everything you search will be sent to and external site where the effective operation is performed.
