So, there are 3 versions of Hover Zoom+ for Firefox now? Ok, the 'Official' version also fails to display the images on Artstation (both on the frontpage and in artists' galleries) the way Imagus does! There's also no Zoom mode, the image just gets auto-resized to fit the window. In Imagus you can zoom it in and out. Otherwise, a decent extension but definitely needs improvements and image preview options
