Default open action for Ubuntu
Something happened on my Ubuntu install sometime which meant that double clicking on an HTML file resulted in the file being opened by gedit . Not really what I wanted. I started looking through the GNOME system menu (Preferences and Administration) to find how to change the default action - but that turned out to be the wrong place. In Nautilus , simply right click on the file and select 'Properties'. From there, go to the 'Open with' tab and select the appropriate application.
