Adobe has released a preview of their upcoming 64-bit version of Flash player for Linux. The software giant has shown much hesitancy towards porting Flash, without much explanation. This release is considered to be in alpha state, but I’ve found no more bugs than in their stable 9.x series for Linux. In fact, I’ve actually had better results overall.
Quit your browser and remove any previous installations of Flash as well as all versions of NSPlugin.
Extract libflashplayer.so and copy it to /usr/lib64/browser-plugins.
Relaunch your browser and verify the installation by either visiting Adobe’s About Flash page or typing in Firefox’s address “bar about:plugins” (without the quotation marks).
If it all went well, you’ll be happily playing the wealth of Flash media online.
Please comment below whether or not it worked for you.
Update: Changed the link to Flash Player “Square.”
