Features & Capabilities

Duolingo expects answers and word searches to be NFC-normalized strings (see the Unicode Normalization FAQ).

But, depending on the input method, those values may contain decomposed characters, making them internally different from their normalized versions.

For example, the Vietnamese word một (one) can be written in (at least) 3 different ways:

một : m \u1ED9 t (NFC)
một : m \u00F4 \u0323 t (VN keyboard)
một : mo \u0323 \u0302 t (NFD)

The extension aims to prevent false positives in typo detection and fix word searches by automatically normalizing relevant inputs.

Is Duolingo Unicode Normalizer 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.

Duolingo Unicode Normalizer requires a few sensitive permissions. 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.

Duolingo Unicode Normalizer has earned a fairly good reputation and likely can be trusted.
