Well, it is about time someone made installing flash easy, especially for Ubuntu 64bit. As usual, I found myself scouring the internet in search of a surefire way of installing flash into Firefox (and maybe even Opera) without any guesswork. Well, I took the best suggestions, from all over the internet and made a single script that just works--EVERYTIME! It does not matter if you are running feisty fawn, gutsy gibbon, hardy heron, intrepid ibex, karmic koala, etc. It does not matter if you are running 32bit or 64bit. It does not matter if you use Firefox or Opera. This script just works. Oh, and it even works with Pulseaudio. So, download the file or copy and paste the script as normal.

Don't forget to chmod +x and run with sudo. Enjoy.

Download Script or copy and paste the script manually:
