The best remote torrent uploader addon on FF. Period. Thanks for making it compatible with FF 57+. But I prefer the old native firefox addon UI.
This one has an unwanted horizontal scrollbar in directory chooser.

Also there is now no option in the firefox default download dialogue to choose remote torrent/box. You either have to activate extension on all torrent files or go for context menu options. I have to disable extension each time when I choose to open torrent file on my local system. I really miss the old firefox addon features.
