User Reviews

This add-on is exactly the perfect extension I had imagined and was looking for! Huge thanks to the developers!! 🙏❤️ The only thing missing is the ability to select custom dictionaries, just like on the Jiten website (which would be really helpful for people like me who aren’t super comfortable with English, for example). It would also be amazing if, one day, we could enable furigana only for unknown and young vocabulary (or only unknown), so we don’t end up relying on them too much for reading. Right now, it’s all or nothing: either furigana are fully enabled or fully disabled 😐. But I’m sure the add-on is still being improved, and the developers have probably already thought about all of this! 🥺 開発者の皆さん、これからも頑張ってください!💪

Is Jiten 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.

Jiten Reader requires a few sensitive permissions. Exercise caution before installing.

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.

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