[rawdez]

Save Image As... in all major gesture addons is broken for instagram urls now, images can't be downloaded using Foxy Gestures, Gesturefy or smartUp Gestures all of them are broken now. https://addons.mozilla.org/en-US/firefox/search/?q=gestures

images like this https://instagram.fdnk5-1.fna.fbcdn.net/v/t51.2885-15/e35/176554630_494241225276150_317025045469686786_n.jpg?tp=1&_nc_ht=instagram.fdnk5-1.fna.fbcdn.net&_nc_cat=106&_nc_ohc=49BYd2DSmwMAX9_Igu4&edm=AP_V10EBAAAA&ccb=7-4&oh=85026b5b0b682aa46804f5f2300af16b&oe=60A9525D&_nc_sid=4f375e result in Failed download when you try to use a gesture for Save Image As....

images should download without a problem or better yet be copied directly from the browser cash to a save folder without redownloading a file.

As @marklieberman already wrote here this is probably a bug in the Firefox download API.
