Default Web Applications top open URL - Opera

when I click on url / HTML links in Thunderbird, it open with Firefox. I want it to open with Opera ( Faster)

I used Default Application to set the default browser to Opera, but it didn’t changed anything

Where else I can specify that ?

"Default Application" ? mmh i think that this is an enlightnement conf but not sure how it works

Try this command and see if opens firefox too:

web-launcher google.com

Also tell me what shows the command:

readlink -f /etc/alternatives/x-www-browser
