Linux下的firefox浏覽器不能播放flash，需要安裝插件 nstall_flash_player_9_linux
因為我的筆記本上沒有安裝Flash Player 9,而許多的Web聊天方式是需要Flash Player 9的支持的，於是下載Flash_Player_9的安裝文件：到這裡下載
[root@localhost ~]# pwd
/root
[root@localhost ~]# cd install_flash_player_9_linux
[root@localhost install_flash_player_9_linux]# ./flashplayer-installer

到這一步之後，我在我的系統中找不到Firefox的安裝目錄了，找了好一會兒，還是沒有找到。在網上找到了一個解決辦法，就是把libflashplayer.so直接復制到browser-plugins文件夾下面，然後重啟Firefox，試了一下，OK，問題解決。
