Features & Capabilities

YuLaF cleans up your YouTube feed by hiding videos that aren't in the languages you actually care about. Pick one or more target languages and only matching videos stay visible — across the home feed, search results, channel pages, and recommendations.

Built for:

Language learners who want maximum exposure to their target language
Polyglots tired of mixed-language recommendations
Anyone who wants a quieter, more focused YouTube

How it works:

Detects each video's language from its title and description using Chrome's built-in i18n API plus character-script validation (Hiragana, Hangul, Cyrillic, Arabic, Devanagari, and more)
Hides non-matching videos in real time, no page refresh needed
Tracks videos filtered, time reclaimed, and your daily streak — all stored locally

Privacy-first:

Zero data collection, zero telemetry, zero remote servers
All language detection runs on your device
Settings sync via your browser's built-in storage, never a third party

Features:

61 supported languages
Multi-language selection (e.g. learn Japanese AND keep English)
Strict mode for higher detection confidence
Customizable keyboard shortcut (default Alt+Y / Ctrl+Y)
Filter activity stats: videos filtered, time reclaimed, active streak
Works on YouTube home, search, recommendations, and channel pages

User Reviews

a great extension for those wanting to learn a language while having fun. I learned English watching YouTube content and this extension would've helped me a lot back then, and will for sure help me now with reinforcement and with learning other languages. :)

Is YuLaF – YouTube Language Filter 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.

YuLaF – YouTube Language Filter requires some sensitive permissions that could impact your browser and data security. 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.

YuLaF – YouTube Language Filter is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
