[Evolution] Opening links in Firefox

[Chris <cpollock embarqmail com>]

I've just installed Firefox from the Mozilla site removing the Ubuntu
version which seems to have been causing my system to lockup. Now when
clicking a link in a message a new Firefox is started in the same window
as Evolution is in instead of opening the link in the window that
Firefox is running in. Is there a setting in Evolution or Firefox
somewhere that will set this back to the way it was?

Thanks
Chris
