Reproducible: Always Steps to Reproduce: 1. Open http://www.basango.com/index.php?action=breve&id_article=1039149 and other tabs. Make sure that the tab that is currently displayed does not correspond to the given URL (otherwise the following problems do not occur). 2. Switch to another application. 3. Click on the Firefox window. Actual Results: * The Firefox window doesn't go to the foreground (if it wasn't already). * The Firefox menu doesn't appear (one still has the menu of the previous application). * The mouse wheel has no effect. * When moving the mouse pointer over a link, the shape of the mouse pointer doesn't change (but the status line is updated as expected, displaying the URL of the link). * Firefox is slow to respond to events. Expected Results: These problems should not occur. When the given URL is open, Firefox takes 100% CPU time.
