View source for Starting chromium as default browser in thunderbird

Thunderbird seems to always start firefox when a link is clicked. This is bad behaviour.

The following command will start chromium:
 gconftool-2 --type string -s /desktop/gnome/url-handlers/http/command "/usr/bin/chromium %s"
This works also in KDE

other solution: jan 2012

 Nothing helped, so I've found other solution:
 1) in Thunderbird go to Edit -> Preferences -> Advanced -> General ->  Configuration Edito
 2) change
 network.protocol-handler.warn-external.http and 
 network.protocol-handler.warn-external.https
 to "true"
 3)Click on any link in tb
 4) navigate to /usr/bin/google-chrome
 5) have fun
