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 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.

Very helpful and practical for translation tasks
Displays translations in a small popup window
Highly rated before recent issues
Easy to use
Supports multiple languages

Cons

Currently unable to connect to Google translation servers, causing errors
Recent updates have broken key functionalities, such as fetching romaji and window focus behavior
Seems to be unmaintained or abandoned after last update in September 2022
Can be slow and overly complex compared to alternatives

Is S3.Translator 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.

S3.Translator requires a lot of sensitive permissions. 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.

S3.Translator has earned a fairly good reputation and likely can be trusted.
