Adds a toolbar button to generate a QR code for the current website. This extension has no external dependencies: The QR code generator is written in pure javascript. This extension adds a toolbar button which, when clicked, displays the QR-code for the current page's URL. The QR-code can be scanned by a mobile device with a camera, using an appropriate mobile application, to open the URL directly on the mobile device. This makes it simpler to send URLs from a desktop computer or a mobile device to another mobile device, thus saving the need to retype the whole address. To generate a QR, simply press on the extension's toolbar button. A popup with the QR and additional controls will appear. You can configure the QR using the controls, and it will automatically be regenerated as the controls are adjusted. This extension differs from other similar extensions in that the QR-code generator is written in pure JavaScript, and doesn't require the use of any website or external resource. This allows using the extension while offline, and maintains higher privacy since the encoded URL isn't sent to any 3rd party website. The JavaScript QR-code generator is an original implementation based directly on ISO 18004. It is not in any way based on or related to any other implementation, and is thus completely license-free. Features:* Pure JavaScript implementation* Very fast. No need to wait for a server's response. QR-codes generated in real-time* Works even when offline, no network connection required* Maintains privacy: Encoded URLs are NOT sent over the network. May be safely enabled for use with secure and private tabs* Original license-free implementation of ISO 18004* Supports any URL type, including "data:" (You must enable the extension to interact with secure sites through the "Extension Privacy Settings" for it to work with "https:")* Click on the generated QR code to view or save as a PNG in a new tab (As of version 1.1)* Option to view or save as an SVG instead of a PNG, accessible via the extension's preferences (Found under the "Manage Extensions" view)* Configurable: The error-correction level can be selected by the user. Defaults to the highest error-correction level which still leaves enough space for the encoded URL* Highly configurable: The size of the QR-code can be selected by the user. Defaults to the smallest size in which the URL can be encoded at the selected error-correction level* Very highly configurable: The false-positive prevention mask can be selected by the user. Defaults to the best-scoring mask as defined by ISO 18004 A note on masks: The score for a mask represents a "penalty". A lower score indicates a better mask. Masks are designed to maintain an even ratio of dark/light areas, and prevent/reduce the appearance of special patterns which might confuse a scanner. The extension's icon is a Micro QR-code, which slightly differs from the standard QR-codes generated by this extension. Unfortunately, there was not enough room for a standard QR-code.
