After updating from FC2 to FC3, (the system is fully updated), My Thunderbird doesn't trigger any more my Firefox, when I go over a ling of the kind http://www. etc etc on any mail I get. They were working fine on FC2, but Mozilla was still there:
What is the point to be investigated (any setting in Thunderbird???)??
Make sure Firefox is your default browser.
Tnx for help
