Features & Capabilities

This extension uses the Sudachi lexical analyzer and the Mozilla Readability.js library to identify the main content of any page and, when the extension is activated, all Japanese text in the main content will be parsed and highlighted. Words matching known dictionary entries or grammar rules (currently JLPT N4/N5/N3 is supported) are underlined in blue. Hovering over words will let you view definitions, part of speech categories, and grammar explanations.

Is iyaku Japanese 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.

iyaku Japanese Reader 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.

iyaku Japanese Reader may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
