Mozilla Firefox puts the downloaded file(s) by default in the user’s Downloads folder. You can set up Firefox to ask where to save the downloaded files, which gives the user more control of where to store the downloaded files. Just go to the Tools > Options and at General tab, set Always ask me where to save files instead of Saves files to Downloads.
This option is useful but not powerful enough. It would be better to create a filter in order to automatically save the downloaded files to selected folders, based on file extension or websites.
The AutomaticSave Folder
extension offers such feature that allows you to specify where each file you are downloading will be saved too. After installing the extension, go to Tools
and select Automatic Save Folder
to configure the options. You may are add some website domain and file name filters at the Filters
tab to determine where the file goes to if it matches the filter
(fined, partial or wildcarded) and regular expressions
