I use Pale Moon 27.6.1 64-bit (a Firefox fork), DownloadStudio, and FlashGot (probably the most recent version compatible with PM). When I have FlashGot set to download media using DownloadStudio and try to download YouTube videos, DownloadStudio commonly gets confused and downloads videoplayback instead of the video. Do you know of an issue that might be causing this?

Below is the string I used to tell DownloadStudio what to do. Is something wrong here?
<downloadstudio><originator>firefox</originator><script><add_jobs display_dialog=yes><joblist><job> [<url>URL</url>] [<url_list_file>UFILE</url_list_file>]
[<referer>REFERER</referer>] [<post_data>POST</post_data>] [<cookie>COOKIE</cookie>] </job></joblist></add_jobs></script></downloadstudio>
