hi, the app doesnt work : the "secondary subtitle" option appears, but the list of subs is empty.

A tremendous add-on deserving praise! Finally me and my partner can watch Netflix together and not have the show ruined when a language which neither of us speak appears. I saw in comments somewhere that it can be a bit buggy. I haven't experienced it...but do reload your browser if you have any issues. When viewing a show on netflix, the add-on should turn red in the menu, (if it is up there), then if you go into the subs menu on the netflix site, you should see an extra secondary sub selection in there. I don't know how they modify the normal website but it's amazing. Also you can open the add-on to tamper with the sub font sizes until they look just right. Bravo and thank you so much creators!!! Me and my partner... and also my other friends who don't speak English - can enjoy shows together without people being left out.

Today the Netflix UI changed. Secondary subtitle dosen't work!

有时会失效，chrome 也一样，只能多换几个节点，多刷新试试了。

It's cool, and help me to listen pratice. But it impact to video that cannot play or start to play. How i fix it?

I was worried since the developer's name is different from the one of same extension in chrome, but it works perfectly fine.

The extension offers almost the same thing as Fleex (it just lacks the possibility to have a tooltip with the definition of the words you want), for free. It works well and is very practical, thank you for that.

However, the source code is not very intelligible (there are a lot of calls to the charCodeAt() and fromCharCode() methods with numbers, it's hard to understand if they are used or not to hide portions of malicious code) and significantly longer than the version released on Github: 36.7KB for the nflxmultisubs.js file on Github vs 140KB for the nflxmultisubs.min.js file in the xpi file. It's a bit dubious, I recommend to use this extension only in a Netflix dedicated browser.
