When you encounter no Flash plug-in when browsing to the official website to download one:

http://get.adobe.com/cn/flashplayer/

The download is: install_flash_player_11_linux.i386.tar.gz

Then unzip the package, and then follow the usual first look at the Readme.txt file. You can see that you want to copy the extracted plugin's library to the browser plug-in folder. Also copy the files under USR to the/usr folder of the system, such as the following in the original document:
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

So now the question is how to find the folder where the browser (Firefox) stores the plugin?

Firefox's company is Mozzilla, so the library should put the folder is in:
/usr/lib/mozilla/plugins/

Copy the libflashlayer.so to the/usr/lib/mozilla/plugins/,
Copy the usr below to the USR folder under the system.

Then restart Firefox to use the Flash plugin.
