Want to change the default download location for Mozilla Firefox? Perhaps you want to have it default to your desktop, or a special folder on your hard drive? To do so, go to the Options menu in Firefox, then under the General tab look for the Downloads section. Browse to a location in the “Save files to” option screen, then click on OK and you should be good to go. Alternatively, you can have Firefox prompt you for a location for every download by choosing the option “Always ask me where to save files” instead.
