I would give this app negative stars if I could. There is no selective way to download files and it automatically download ALL the files among launching a download which is not what I wanted. There are over 1000 files in the same format on this website and without being able to get only the files I want it is useless to me. Worst of all there is no way to stop the download and I have to disable the add-on and force-quite my firefox to stop this app from feeding my computer with junk files.
