Features & Capabilities

BilingualTube - YouTube Bilingual Subtitles

Watch YouTube videos with bilingual subtitles. Display original and translated subtitles simultaneously to improve language learning and video comprehension.

Key Features: • Bilingual subtitle display - Shows original text and translation together • Official translation support - Uses YouTube's native translations when available • API translation fallback - Supports Microsoft Translator (no API key required) and OpenAI • Smart language detection - Automatically detects source language and handles language variants • Clean interface - Subtitles overlay directly on the video player

How it works:

Install the extension
Open any YouTube video with subtitles
Configure your target language in the extension options
Bilingual subtitles appear automatically

Translation Options: • Microsoft Translator - Free, no configuration needed • OpenAI - Requires API key, supports custom prompts and models

Perfect for: • Language learners who want to see both original and translated text • Viewers who prefer subtitles in their native language • Anyone watching foreign language content

The extension prioritizes official YouTube translations for better accuracy, and falls back to API translation when official translations are unavailable.

Privacy: No data collection. All translation requests go directly to your chosen translation service.

Works great! (if could also set the color of the subtitles in different languages, it would be 6*)

Is BilingualTube 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.

BilingualTube requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

BilingualTube is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
