User Reviews

Across multiple reviews, the add-on is criticized for high costs and paywalls, missing image translation (no OCR), security/privacy concerns due to data leaks, and intrusive automatic translation. Positive feedback is scarce and largely isolated to single reviews, with a few mentions of improved translation versus Firefox’s built-in tool or subtitle-related capabilities. The most consistent themes are price, feature gaps (image translation), privacy issues, and auto-translation behavior.
Pros
Cons
  • High price / paywall: subscription is seen as expensive and restricts features unless paid, with questions about API pricing.
  • Does not translate images / OCR: image translation is not supported, limiting usefulness.
  • Security / privacy concerns: reviews mention data leaks and suspicious handling of user data.
  • Automatic translation is intrusive: auto-translation distracts while reading and is hard to disable.
