It has Netfliix typo so it's the best add-on, you should totally use this one

安裝此插件以後看影片五分鐘左右字幕就會變成''試用結束'',有甚麼辦法恢復嗎?是要付費嗎?

simple, easy to use. just set the programme language as the primary subs and your language as the secondary and it works no problem

Oh wow, this works better than I expected. No issues whatsoever so far, it's plug and play. It even plays nice with my other addons that alter the netflix UI.
I may have a suggestion: would it be possible to include an option to add furigana? Maybe even make them easily toggleable by keyboard shortcut? Right now I'm using 10ten Reader on top of this addon to get readings where the audio isn't clear enough, which does work but it's a bit clunky. I do realise that the add-on would have to pull the readings from somewhere which probably wouldn't always work perfectly (and might be too resource-heavy?) but I think this could help even more with listening comprehension.

It works very well. Really helpful!

Exactly does the job what it is required to do. Also it customizes subtitle!

EDIT: This review was produced in a system with Arch Linux using firefox.

Just what I've been waiting for. Works great. Thanks a million for this.

Just what I need, works perfectly with no hicaps as if it's part of the site and not a third party extension.
And extra functionality is wonderful and well though. Love the make subtitles selectable one) Deservies 6 stars out of five!
The only thing I wish is the possblity to change font color of the Secondary subtitle sepratly of the Primary one just like with size.

Hi, since today it doesn't work at all. Tested also in a new profile.

[EDIT]
Version 3.9 is OK, the wifey no longer shouts at me, thanks for fixing!

Works great thank you! Only mild inconvenience is that I sometimes have to disable/enable the subtitles for them to show up.

Incredibly useful for language learning. I haven't spotted any issue yet! Thank you so much for this useful Addon!

真的不错！！我网飞字幕的字体大小调整不了，装了这个就可以了，还有双语字幕，支持支持！

Works great, and the options to adjust subtitle font size are super!
