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
