This simple script will add the flash plugin to Chrome.
Please make sure that google chrome is updated as only the newer versions support plugins.
Simple script for default configuration:
This assumes that flash is installed in /usr/lib/adobe-flashplugin/ and google chrome in /opt/google/chrome/
1) Install flash:
If you haven't already done so, then download and install flash from the adobe website.
2) Run the script:
cd /opt/google/chrome/; sudo mkdir plugins; cd plugins; sudo ln -s /usr/lib/adobe-flashplugin/libflashplayer.so
3) Edit the launchers:
Click on System > Prefernces > Main Menu
Then select Internet > Google Chrome
Select edit and change the launcher to
/opt/google/chrome/google-chrome --enable-plugins %U
If you have any other launchers on the panel or desktop, right click on them and select properties and then do the same.
Not so simple way: via gui
You need to find the flash plugin folder, if you can't find the /usr/lib/flash-plugin/ then you may also find it in the firfox/plugins folder. Now you need to make a folder in your chrome directory called plugins. Either copy into or make a link to "libflashplayer.so" in that folder.
After this do step 2 of the simple method.
I did this and youtube works for me, haven't tested anything else yet.
