Problems with Flash Plugin

After I have installed the Flash plugin, Arora and Firefox crush after ~10 seconds. These are the logs: [fale@localhost ~]$ firefox sh: acroread: command not found /usr/lib/firefox-3.5b4/run-mozilla.sh: line 131: 4018 Segmentation fault "$prog" ${1+"$@"} [fale@localhost ~]$ arora Oxygen style has been detected, loading Plastique style. - KDE's 4.2's Oxygen style has too many issues with Qt 4.5 features that Arora uses and while many of the issues have been fixed for KDE 4.3, KDE 4.2 users get a really ugly Arora. Once KDE 4.3 is released this check will be removed. If you are still want to use Oxygen add the arguments -style oxygen on the command line. sh: acroread: command not found (process:4124): Gtk-CRITICAL **: gtk_clipboard_get_for_display: assertion `display != NULL' failed Adobe Flash Player: gtk_clipboard_get(GDK_SELECTION_PRIMARY); failed.
