** Stopped working
It shows the available subtitle as a link, but nothing happens after clicking on the link.

It's works greate! thanks. 잘작동합니다. 여러언어 자막도 받을 수 있습니다.

subs are important especially when the darn vid is in Spanish

want it

Just testing this add-on. Working great. Thanks.

It worked swell with old YouTube's layout but new one ruined it.

DOES work with Firefox ESR v52.9. Does NOT work with Firefox Quantum v.60. WHY does Mozilla make such useful extensions so hard to use???

Just found this add-on today. Download and try with a Youtube movie. Works great.
Thank you very, very much.

It doesn't work anymore :(

UPDATE: It's working again, yay! Thanks for updating it, and thanks for making it!

If this addon also converted auto-generated subtitles in an update, THAT would be incredible (I had to piece together an AutoHotKey script to be able to do it, but it's clunky and doesn't do nearly as well as the pure download of the srt file this addon offers).

Thanks again!

Recently it does not work properly. It cannot check out if Youtube video has subtitle or not. Therefore closed captions of some videos can not be downloaded.
It worked very well before. But not now.

I'm not very keen on using add-ons and any other kind extensions for their notorious ability to cause every type of corruption of browsers' functionality but this is a much needed add-on for a person that watches English-speaking YouTube videos and doesn't want any unknown word to slip through his attention for later scrutiny in order to extend his/her learning ability. Sadly more and more YT videos adopt auto-generation of subtitles which this add-on can do nothing about. Auto-generation as it comes from the notion's definition occurs at run-time only, so there's no technical option to extract subtitles stream. I was able to download a SRT file only for one video so far.

It's a good add-on and it works, but not with caption !

Very Nice! Thanks so much! :D
