User Reviews

Users praise the add-on as a simple, lightweight QR reader that reliably decodes codes via a right‑click context menu. Common complaints are that it needs enabling/initial setup after install and has scanning limitations (local/new‑tab images, cropping issues, and some codes requiring online recognition). Overall: effective and minimal, but with usability and capability caveats.

Pros

Reliable QR decoding — multiple users report it successfully reads QR codes.
Simple, no-frills user experience — uses a right‑click "Decode QR" context menu with no extra toolbar clutter.
Lightweight/minimal extension that doesn’t add UI clutter and is easy to use once enabled.

Cons

Requires initial setup/enabling after installation — a couple of users found it tricky to get working at first.
Limited scanning capabilities — several users reported problems scanning local images or images opened in a new tab, cropping/recognition failures, and that some codes need online recognition.

Is QRCode 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.

QRCode Scanner requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

QRCode Scanner may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
