User Reviews
Users praise Mouse Dictionary for Firefox as a convenient, fast tool that shows hover definitions with minimal delay and improves reading on web pages and PDFs. However, there are recurring concerns about usability—the interface and settings are not intuitive, and guidance on accessing preferences is lacking. Maintenance is another worry, with multiple reviews noting that the Firefox version is not updated recently. Overall, the add-on is highly useful and performant, but onboarding and ongoing maintenance could be significantly improved. Pros
- Very convenient and useful for everyday dictionary lookups.
- Fast and responsive hover-based dictionary with near-zero latency.
- Improves reading experience on websites and local PDFs, enabling easy, one-handed reading.
- Works across PC and mobile contexts, broadening where you can look up words.
- Provides solid dictionary entries and examples, aiding comprehension.
Cons
- UI/UX is not intuitive and the setup can be confusing.
- Guidance for accessing and using Firefox preferences/settings is lacking.
- Firefox version updates are infrequent; the add-on feels out of date.

Android端末にはiceravenブラウザを使用。（前はkiwiを使っていました）
辞書データは英辞郎の購入がおすすめです。486円で一度買えば何度でも再ダウンロードが可能。（私は2019年に買いましたが、先日2024年修正版をDLしました）
ただし辞書データを入れるときはテキストを分割して複数に分けて入れないと途中でタイムアウトしちゃってうまくいきません。（私が安価で非力なエントリーモデルを使ってるせいかも）

Please, include a guide of how to get to the preferences site on Firefox. It is not the same as the Github guide, and I had no idea where to go

Is Mouse Dictionary 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.
Mouse Dictionary does not require any sensitive permissions.
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.
Mouse Dictionary has earned a fairly good reputation and likely can be trusted.
