You may need to make a symlink to the plugin at ~/.mozilla/
Like so:
Code:
$ mkdir -p ~/.mozilla/plugins
Dependent on which architecture you're running, either:
Code:
$ ln -s /usr/lib/mozilla/plugins/libflashplayer.so ~/.mozilla/plugins/
Code:
$ ln -s /usr/lib64/mozilla/plugins/libflashplayer.so ~/.mozilla/plugins/
