* openSUSE: 11.3
* KDE: 4.4.4
* Firefox: Mozilla/5.0 (X11; U; Linux x86_64; pl-PL; rv: Gecko/20100626 SUSE/3.6.6-1.2 Ant.com Toolbar 2.0.1 Firefox/3.6.6

When I KRun an URL such as http://forums.opensuse.org, Firefox opens the Web page but it does not acknowledge the action, and the Plasma animated bouncing pointer keeps bouncing until it times out. Moreover, Firefox does not come to front if it is already running in a background window. If I activate the Firefox window, the bouncing pointer leaves traces on the rendered page, distorting the picture.

The problem does not occur if Firefox is not running yet.

Other URL-aware applications, such as Konversation, do not have this problem.

The problem appeared after I installed openSUSE_11.3. My previous release was openSUSE_11.2.
