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

Yes, that is it. It is Settings/Settings Manager/Preffered Applications. Thank you laurent! – Aja Oct 13 '12 at 13:10
Sorry for the wrong menu names... I will correct. My version is not in English :) – laurent Oct 13 '12 at 13:12
The problem is that it does not work at least in two cases: 1) opening a link in Thunderbird still launches Firefox 2) running "ubuntu-bug" also opens Firefox Any soulution which would cover all the cases? :/ (using Xubuntu 15.04, clean install; using Chromium as default browser) Thanks for help! – crysman Jul 17 '15 at 11:14
This has solved the problem – crysman Jul 20 '15 at 15:42
PS: still changing it also in xfce4-settings-manager -> Preferred Applications is needed – crysman Nov 7 '15 at 22:07
