S3.Translator

S3.Translator adds the power of Google Translate’s automatic translations to your browser! It supports translation of selected text, entered phrase or whole webpage between any of 100+ languages. New Feature: Language learning!

S3.Translator is a powerful browser extension that leverages Google Translate's public API to provide seamless translations of selected text, phrases, or entire webpages across over 100 languages. Unlike many other translators, it retains HTML formatting to preserve website layouts during translation.

The extension includes innovative new features such as automatic subtitle translation on YouTube, text-to-speech for selected words or phrases, and a unique Language Learning mode that helps users study new languages directly while browsing. It supports auto-detection of source languages and offers convenient shortcuts like full-page translation. S3.Translator enhances browsing experiences by breaking language barriers while enabling both translation and language acquisition.

User reviews

Users appreciated S3.Translator for its practical translation features and the mini window display, praising it as a useful tool. However, recent updates introduced connectivity issues with Google servers, breaking core functionality and causing frustration. The flying window feature also ceased working as expected. Some users find the extension slower and more cumbersome compared to other simpler, faster translation tools.
Pros
  • Provides translation in a mini window, which is convenient for quick reference.
  • Was highly rated by users before recent issues.
  • Useful and practical for translating text.
Cons
  • Recent updates caused connection errors to Google servers, rendering the extension non-functional for several days.
  • The 'default behavior of flying window: Close when loses focus' option stopped working.
  • One review noted that the extension is unnecessarily slow and heavy compared to simpler, faster alternatives.

Extension safety

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.

S3.Translator requires a lot of sensitive permissions. Exercise caution before installing.
