If you installed the extension from the zip before, please remove it and reinstall from the store.

Known Issues

• Wait for the Netflix home page to finish loading completely before starting a show/movie.
• Refresh the page if the secondary sub list is empty.
• This extension could conflict with other Netflix-related extensions (but not NflxIntroSkip! :D). If you encounter any problem, try to disable some of them
• RTL (right-to-left) text-based subtitles are not ready yet
• This extension and the developers are not affiliated with Netflix, Inc; All rights belong to their owners

Problems?

The secondary subtitles list is empty or subs aren't showing up

• Subs will show up after a Refresh (F5).

Large gap between main subtitle and secondary subtitle

• This happens only when the controls bar is active -- just wait until the controls hide

Only available in Chrome/Firefox for desktop?

• Yup -- mobile devices, smart TVs, Apple TV, Chromecast, … are not supported

Could I load subtitles from other country?

• This extension respects Netflix rules, hence we only support all official subtitles available in your country

Feature request: __________ ?

• This extension does one thing and does it well -- great experience with bilingual subtitles support
• If you have a request you can open an issue for consideration (please put [Feature Request] in the title)

Donate

The extension is and will remain free. If you like and want to support my work, donations are welcome.
