Features & Capabilities

QR Region Scanner lets you read a QR code anywhere in your browser without a phone or a separate app.

Press the keyboard shortcut (default Ctrl+Shift+Y) or click the toolbar button, drag a rectangle over the QR code, and the extension decodes it instantly:

If the code is a web link, it opens in a new tab.
If it is anything else (plain text, WiFi details, and so on), the text is copied to your clipboard and shown in a notification.

Key features:

Works on normal web pages, and also on pages other extensions cannot reach, such as Firefox's built-in PDF viewer and reader mode. On those pages it takes a quick screenshot of the tab and lets you select the region on the captured image.
Configurable shortcut. Set your own key combination in the add-on preferences.
Fast, private, and offline. Decoding happens entirely on your device. The extension makes no network requests and collects no data.
Minimal permissions. It only reads the current tab when you trigger a scan.

Note: a browser extension can only see the content of the current tab, so it cannot scan the browser's own interface, other windows, or your desktop. A few fully privileged pages (such as about:pages and addons.mozilla.org) cannot be captured, but they do not contain QR codes anyway.

Uses the open-source jsQR library (MIT) for decoding.

Is QR Region Scanner Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

QR Region Scanner requires very minimum permissions.

Risk impact analysis details

High Allows reading and modifying clipboard content, which can be sensitive, posing a moderate privacy risk.
Medium ******* ******* ************* ***** *** ** ******* *** **** ******* ****** ******** *******

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

QR Region Scanner is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
