Hi, Opensuse 12.3, KDE My standard browser in system settings is seamonkey. Thunderbird used to open links in emails in a new tab in seamonkey. To try something I changed the about-config-setttings in thunderbird: network.protocol-handler.warn-external.http and network.protocol-handler.warn-external.https from false to true. As expected I was asked the next time which browser to use and I selected firefox. All fine. But now I want to go back, i.e. so that links are opened in seamonkey again. I can't. It keeps opening firefox and I find no way to change that again. Where do I have to search? All I find in big-brother is the description of what I did above. But how to revert? I changed several times from false to true, from true to false, always with closing thunderbird per menu, even with logging out and in as user. No change. I am confused. What can I do? b.t.w. network.protocol-handler.app.http and network.protocol-handler.app.https are set to seamonkey (/usr/bin/seamonkey) thanks for hints Daniel -- Daniel Bauer photographer Basel Barcelona http://www.daniel-bauer.com room in Barcelona: https://www.airbnb.es/rooms/2416137 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
