I have several computers of my own running 12.04 and Firefox automatically calls Ktorrent when I click on a .torrent file, however, I am setting up a friend's computer to use Ubuntu 12.04...and his computer doesn't have copies of my own personal configuration files which evidently carry forward this ability for my own computers as I install new versions of Ubuntu.....and I seem to have forgotten how this is done or something has changed dramatically!
This is his first experience with Linux and I can't seem to get his firefox browser to do the same automatic action! I have been googling for an answer, but everything I find has directions that seem to be far outdated and no longer applicable.
What do I need to do to make his Firefox browser automatically hand a .torrent file to Ktorrent???
Thanks for your thoughts and suggestions!
