i tried to install flash plugin from the browser(firefox) automatically and it says fail.i don't want to install it from source.is there any way to install it with yum ?
try to install the plugin as root and not as user (as you might have tried)
on the terminal enter xhost + to enable root to use the display
su
Password *************
firefox
visit a trustable site which requires the plugin to force an installation
afterwars you can close the root-firefox and restart user-firefox to enable the plugin
