Installing flash for firefox is fairly easy. What version of Ubuntu did you install? Anything from 10.04 should have installed it automatically. If not then download and install this: http://launchpad.net/ubuntu-tweak/0.5.x/0.5.14/+download/ubuntu-tweak_0.5.14-1~natty1_all.deb Then go through and pick what you want and install as much as you want.
