Description from store

Best ever Chrome/Firefox extension to unleash bilingual subtitles on Netflix!

This is a fixed and updated re-release of the original NflxMultiSubs. This version contains a fix for the 2021 Netflix redesign that broke the original, and has various other bugfixes and improvements.

Click on the extension button to access the extension settings.
Note: this extension will only show the subtitle languages that are available in your country.

Features:
- Enable secondary subtitles in the available languages (incl. image-based subtitles like Japanese, Chinese, Russian, …)
- Smart selection on secondary subtitles. Choose between 3 subtitle activation modes: disabled; automatically match subtitle language to audio language; or remember the last selected language.
- Seamless integration with native Netflix player UI -- switch languages in place
- Adjust playback speed with a hotkey ( [ and ] )
- Free and open source!

Report bugs by creating an issue on Github (https://github.com/gmertes/NflxMultiSubs) or send me an email (click "contact the publisher" on the right of this page).

Excellent extension

Lay Tsai 2025-08-09

In the latest version, if the video's resolution/ratio is different from your monitor, when you enter full screen mode, the video will glitch (position shifting) when the subtitles appear and disappear. In my case, most videos' ratio is 16:9 while my monitor is 21:9, and it triggers the glitch. But if the video is also 21:9, then everything works fine.

Simple. Get the job done.

Jack Liu 2025-06-29

this is really well done! I tried to develop something similar vibe coding with ai, but mine relies on translations api from google which lags, the speed on this is basically same as the native subtitle! I gave up working on mine and just downloaded this haha I do wish this has width control: so that I can prevent the native subtitle from forming into 2 lines I also have notice the text color for the 2nd subtitle works only on English.

Xorea 2025-05-30

doesn't work, the subtitles are always at least half wrong compared to what is actually being said.

Zhou Vic 2025-05-18

good software

Stacey 2025-03-05

This extension was awesome, please please fix it!

Sheena Knudstrup 2025-03-04

I loved this extension, sadly chrome no longer supports it so it's now useless :(

Severin Sieber 2024-09-27

without any of the extra visual clutter or paid features of the competitors. does its job perfectly

Charlotte 2024-07-06

It doesn't work when skipping to the next episode. Please fix it, thank you!

Mathew Boorman 2024-07-03

Yes it works. Sadly the other 'freemium' plugins seem to be impossible to find important details like pricing or have super broad permisions. Open source FTW. I just wish it had the replay last line hotkeys like Language Reactor.

Rachel Tan 2024-06-29

works well. thank you!!

unknown unknown 2024-06-26

Works like a charm! And it's completely free! (at least it seems I haven't been asked to pay so far). I'm so grateful to the creators of this app for this kind and generous offering of this invaluable tool!

JGH 2024-06-23

works great.. very clean

Laura Rainsford 2024-06-23

Refreshing Netflix is an important step!

Mahmoud Omar 2024-05-24

really helpful thanks but both of subtitles are overlapped what is the way to separate them ?

Papon Wappen 2024-05-18

Holy it works, I had to jump from original github repo (not maintained anymore, not worked) , find fork, and finally found this maintained one. F The another one extension that required subscription payment.

Sss Z 2024-04-26

Puzzle P1X3L 2024-03-09

It works very well, helps my language study a lot!

C A 2024-02-13

excellent and free.

雙字幕很好用感謝 希望能設定字幕字體+粗體樣式+陰影邊框 很喜歡預設的日文副字幕字體,可惜主字幕無法更改,但了解作者主要功能就只是為了雙字幕,最後就四處找了CSS來更改字體+外框https://greasyfork.org/zh-TW/scripts/486313

I wish there was Pinyin included for Chinese...it's a lot easier to learn how to speak with the pinyin and tone intonations. Hopefully with any future updates, this can be added please!!
