看视频，听歌都不行，肯定是插件问题了。

下载install_flash_player_11_linux.i386.tar.gz文件到本地，解压然后阅读readme文件，
Installing using the plugin tar.gz:
o Unpack the plugin tar.gz and copy the files to the appropriate location.
o Save the plugin tar.gz locally and note the location the file was saved to.
o Launch terminal and change directories to the location the file was saved to.
o Unpack the tar.gz file. Once unpacked you will see the following:
+ libflashplayer.so
+ /usr
o Identify the location of the browser plugins directory, based on your Linux distribution and Firefox version
o Copy libflashplayer.so to the appropriate browser plugins directory. At the prompt type:
+ cp libflashlayer.so <BrowserPluginsLocation>
o Copy the Flash Player Local Settings configurations files to the /usr directory. At the prompt type:
+ sudo cp -r usr/* /usr
我使用的是ubuntu 12.04 32位：
1；sudo cp libflashplayer.so /usr/lib/firefox/plugins/
2；sudo cp -r usr/* /usr/
通过这2个步骤，就可以搞定了。
