USE IT AT YOUR OWN RISK! THIS IS NOT AN OFFICIAL RELEASE. THERE ARE NO GUARANTEES OR WARRANTIES. Im not claiming ownership or anything else, I just "twicked" it a bit to make it work. Because APPLE and ADOBE don't give a sh1t about PPC anymore.
Here is the last available version of Flash Player plug-in for PCC Macs that will let you view embedded YouTube videos in Facebook. Currently if you are on a PPC Mac and you click on videos in Facebook and some videos on CNN and some other sites, it will tell you to update to the new Flash Player... THERE IS NO NEW FLASH PLAYER FOR PPC MACs.
PPC architecture is officially no longer supported by APPLE or ADOBE.
Download to your desktop, unzip it, and read the instructions... I tried to be a clear as possible.
