File Router от DeGagne Consulting

The extension will locate the source domain for the download and save it to a sub-folder matching the domain. If necessary it will create the sub-folder first.

Because Firefox does not have the function necessary to simply perform the reassignment of the download, it is using a work around. If the extension fails to work make sure you have the latest version of Firefox and the extension. Turn it off if that still doesn't fix the problem.

Not all domains can be tested so if you encounter one that doesn't work, the extension will attempt to download to your default directory. If that doesn't work please turn off the extension temporarily and attempt again. Please report the file you are attempting to download to my email address and I will try to take a look at the problem.

Note: No personal data is collected by this extension, The necessary data that is collected is the domain,directory and filename of the file you are attempted and is stored locally on your machine. None of this data is collected by the author.
