User Reviews

The QR Code Reader Firefox add-on is praised for its reliable and straightforward functionality, allowing users to scan QR codes via screenshots, drag-and-drop, or uploading images. Many users appreciate its ease of installation and clean interface without ads. However, several users find the need to manually capture and load QR code images inconvenient, and the add-on opening in a separate tab instead of a popup is seen as a minor drawback. Some confusion arises from mismatched user expectations about scanning capabilities directly from the web page.

Pros

Accurately reads QR codes from images with ease.
Simple installation and straightforward to use.
Supports drag and drop and copy-paste of QR code images for scanning.
Works well and reliably as described without unwanted ads or malicious elements.
Allows scanning from webcam or local files by clicking its toolbar button.

Cons

Requires manual screenshot or image preparation to scan QR codes—does not scan codes directly from webpage without extra steps.
Interface opens in a separate tab which some users find inconvenient.
Confusing for users expecting instant scanning from web images or integrated functionality without additional steps.

Not much of a browser extension, I wanted to scan a qr code that was on the web page and I thought rather than having to screenshot it maybe there's an extension for this. Well this one isn't it, it just opens a new window where you have to either use a webcam or use a screenshot. If I'm going to have to screenshot it then how is this any better than zbar?

Does exactly what it says it can do. Easy to read QR codes from the website by using the Firefox screenshot tool to copy and pasting (ctrl v) it for the addon to read the code and convert it to a link. Thank you for making this. Cheers.

Is QR Code Reader 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 Code Reader does not require any sensitive permissions.

Risk impact analysis details

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 Code Reader is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
