Changing default browser in xubuntu

xubuntu comes with Firefox as a default browser. I however prefer opera and would like to make it my default browser. Example: I click a link in Thunderbird and would like it to open in Opera and not in Firefox, as it is now.. How do I proceed?


In XFCE you can change the default browser (and other default applications like the File manager or the e-mail client) using the main menu: Settings -> Settings Manager -> Preferred Applications
