This addon is really awesome and really helpful for learning new language or watch movies online.
but need a little more work:
1- the ability to change the subtitles style/font size are not working.
2- Synchronization option doesn't show up.
3- No way to loaded different subtitle if first one was wrong.

great add-on. can always find the subtitles I need.

This is truly an awesome extension.

This is a good add-ons, and i can add subtitles when i playing some videos on my vps.

very good add-on, provided searching sub directly (event i dont know where it source)

It is true it runs on any video on the web. It is easy to use and has all the features it promises.

Fantastic, one-of-a-kind extension! I looked for a subtitle player and this add-on was the most flexible one. I mostly use it as a layer and this is a feature other addons are lacking. Full screen by definition brings the video to the foreground, so no subtitles on top, there is no workaround yet within FF (still I can press F11 and zoom the page in to make video almost fullscreen).
I wish I could try new v2, but I press the button and the popup menu is blank. Maybe it's my old browser, FF 47.0.2, I think it's not any other extension. Anyway, I give the dev 5 stars because it's awesome! Thanks!
