Allows you to download subtitles from Amazon Video
< Feedback on Amazon Video - subtitle downloader
On amazon.com or primevideo.com? Because I just tested The Family Man S01E01 (this ep is free) on amazon.com and it downloaded subs just fine.
Subtitle are there but only these two episodes can't be downloaded. I had to use the chrome's developer tool to download them. Thanks anyway.
Not my script's fault, it's one of the subs server not sending a proper CORS header. Try with 1.7.2, it should work now. The script uses GM.xmlHttpRequest now to bypass that.
Can't dl some episodes' subtitle
Such as The Family Man S01E01 or Chicago P.D. S01E09. Not sure why.
