On Firefox 1.0PR when I clicked on a link that was on my desktop or on a messenger window, it opened a new firefox window to load the contents there.
On a previous version (0.7 I think) it opened a new tab on the firefox window I had open and minimized.
On RC1 it replaces the page I'm currently viewing and it bothers me.
How can I change it to open a new tab or a new firefox window? I guess it should be on about:config somewhere.

ooo:O I found it, it's the
browser.link.open_external
where 1 = load on current window (replace current page), 2 = load on new window, 3 = load on new tab

advanced.system.supportDDEExec

Try that one. Should be False.
