Features & Capabilities

LinguaLens turns everyday reading into vocabulary practice. On supported webpages and in supported YouTube subtitles, eligible occurrences of words you have studied can appear in your target language when the matching, context, and grammar pipeline can establish a safe result. Hover review controls and FSRS scheduling turn those encounters into retrieval practice. Import from Anki or Skritter, choose a starter deck, or build your own. Privacy-first: when contextual resolution is needed, LinguaLens sends only a bounded, short visible-text clause around the studied word—never full pages, URLs, or browsing history.

Is LinguaLens 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.

LinguaLens 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.

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