User reviews

Blackbox is praised for its accurate OCR technology that streamlines extracting text, saving time and boosting productivity. Users find it very easy to use and highly recommend it. However, multiple users express frustration over mandatory account creation without clear reason, repeated sign-ins, unclear upgrade or pricing details, and occasional functionality issues. Additionally, the absence of a native Linux version restricts its accessibility for that user group.

Pros

Highly accurate OCR capabilities that significantly improve productivity for content creators and researchers.
Easy to use with straightforward text extraction from images and documents.
Saves a considerable amount of time by eliminating manual typing of text from sources.
Positive user recommendations highlighting its efficiency and usefulness.

Cons

Requires users to create an account without clear explanation, causing trust and privacy concerns.
The extension sometimes requires repeated sign-ins when reopening the browser.
Lack of clarity about pricing, credits, or benefits of upgrading, leading to user confusion.
Reports of the extension not working or becoming non-functional over time.
No native Linux version available, limiting usability for some users.

Extension safety

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.

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

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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 Browser Add-ons, 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.

Blackbox has earned a fairly good reputation and likely can be trusted.
