Features & Capabilities

LR by drip7boi brings YouTube dual subtitles to Firefox for Android. Look up words and replay sentences while learning with videos. Use it inside Firefox on your Android phone or tablet; it does not run inside the YouTube app.

A PAID ACTIVATION CODE IS REQUIRED Please read the purchase information before installing: https://lr.491746.xyz/buy/?source=android_amo_description An activation code for this build does not include an upstream Language Reactor subscription. Translation, account features and saved words may depend on upstream services and a separate account.

LEARN ONE SENTENCE AT A TIME Compare bilingual subtitles to follow the original speech and its translation. Use word lookup for unfamiliar vocabulary and sentence replay for focused listening practice. These tools support language learning, including English learning with YouTube. Subtitle translation depends on available captions and services; some videos and page types may not work.

GET STARTED

Install and enable the extension in Firefox for Android.
Open YouTube in Firefox and enter your paid activation code when prompted.
Open a captioned video, select subtitle languages, then check that subtitles and translation are visible.
Tap a word and replay one sentence.

SUPPORT AND LIMITS A loaded panel does not necessarily mean subtitles or translation loaded successfully. Check captions, language settings and account sign-in first. If activation cannot connect, check your network and retry; do not repeatedly uninstall or purchase another code. Android device compatibility still requires testing.

INDEPENDENT COMPATIBILITY BUILD This is an independently maintained compatibility version by drip7boi, not an official Language Reactor release. It is not affiliated with or endorsed by Language Reactor. Firefox and YouTube are named only to describe compatibility.

If you leave a review, please describe your actual device and experience. Do not include activation codes, account details or private diagnostic information.

Is LR Dual Subtitles for YouTube 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.

LR Dual Subtitles for YouTube 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.

LR Dual Subtitles for YouTube is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
