this is a feature called Focus stealing prevention, google find a good description at http://mail.gnome.org/archives/desktop-devel-list/2004-December/msg00306.html
"Focus stealing prevention is active in Metacity. Roughly, it means that if a window was launched at time A, and the user interacted with a different window at time B, and B>A, then the launched window will not be focused when it appears. This allows a user to work with an application while impatiently waiting for that really slow app (*cough* OpenOffice *cough*) to show up without being interrupted mid-thought when it finally does. It also prevents those annoying Instant Message windows from taking your keystrokes and sending them to someone when you meant to be typing them into the application window asking for your root password." i am going to mark this bug report as rejected, but feel free to reopen it and argur you case if you dont agree. ** Changed in: firefox (Ubuntu) Sourcepackagename: firefox => metacity Status: Unconfirmed => Rejected ** Changed in: metacity firefox (Ubuntu) Binarypackagename: firefox => None -- Firefox windows do not get focus when launched https://launchpad.net/bugs/41623 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
