Using download manager in Ubuntu

Using download manager in Ubuntu is not straight forward. A few works needed before using download manager in Ubuntu specially with firefox. First of all you'll have to have flashgot plugin installed in firefox (remember, flashgot works as a communicator of the download manager with the browser, it has no ability to work as download manager itself).

For that you'll have to search for the addon and then add it.
Firefox will be restarted then.


Now install any of the download managers for ubuntu for using download manager in Ubuntu (Gwget, kget, wget, aria .....)

To install them go to terminal and write
sudo apt-get install xxx (where xxx = name of the download manager)

Some has recommended "wxDownload fast" as a good download manager available from "http://dfast.sourceforge.net/download.html". (I didn't give it a try but soon I'll)


From now on whenever you start download a file, there will be a new option - to save with fashgot. In the flashgot menu you'll get the option to download with the download manager.

If flashgot menu doesnot appear, try restarting the firefox.
Now you are ready for using download manager in Ubuntu.
