## Description

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.

## Review summary

Users have found S3.Translator very helpful and practical with useful features like a popup translation window. However, recent updates, especially since September 2022, broke critical functions causing connection errors to Google servers and missing romaji translations. Some users report that window focus settings no longer work, and the extension feels slow and heavy compared to simpler alternatives. Overall, the extension was highly rated before these issues, but currently suffers from lack of maintenance and connectivity problems.
