Allows you to download subtitles from Amazon Video
< Feedback on Amazon Video - subtitle downloader
According to this thread it's broken on amazon pages https://greasyfork.org/pl/forum/discussion/49613/x Don't have account so I'm probably not going to fix it.
Script should be fixed now, I added support for .co.jp but couldn't find any subs. If you can find a video on .co.jp with subtitles that can be turned on or off (so not hardcoded) send a link here.
Anyway, really thank you a lot !
Add support for "amazon.co.jp" would be awesome! thx!
Really great work, help a lot, THX!
