I don't think this is a problem in package mozilla-thunderbird. It might be better to assign it to kde-guidance, kcontrol or even the package that contains update-alternatives (I don't know which one it is).
** Summary changed: - Thunderbird (and other Gnome apps) use konqueror as web browser + Kubuntu setting default components don't affect gnome/gtk apps ** Description changed: Binary package hint: kubuntu-desktop - I´ve installed firefox and set it up as my default web browser in the system settings. But when I click on a link in thunderbird konqueror is still opened. - Since thunderbird uses firefox e.g. in SuSE I think this is a configuration bug. Thunderbird should use the web browser set as default in "kde components" if possible. + I´ve installed firefox and set it up as my default web browser in the + system settings.

UPDATE: This affects all Gnome applications, such as Open Office, as well. To overcome this, sudo update-alternatives --config x-www-browser needs to be run. The same effect should be achieved from within the GUI. -- Kubuntu setting default components don't affect gnome/gtk apps https://launchpad.net/bugs/52670 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
