I’m wondering why the
FilenameConflictAction "prompt" (for
downloads.download()) is not supported for WebExtensions? It was working in the old extensions.
From my point of view, this was the only suitable option for downloading, as you get notified if the file already exist. I don’t want to have the file twice (why should anyone want to have the same file on disk twice? - and even if it is a different file version, the old one is most likely obsolete now). However, simply overwriting the file may also be wrong as one may accidentally overwrite a file which he wanted to keep.
