In some cases the status message "Failed" with an orange dot icon appears _during_ (!) the process of saving. Despite that a file is created on the disk a bit later after the message appeared in the download list. The saved file contains some information from the webpage. But in this situation user cannot be absolutely sure if the saving process is complete and successful according to the status message.
