JavaScript install

[bob brazie]

I have just done a clean install of 9.10 and when visiting YouTube and trying to view a video in Firefox I get this message:

"You either have JavaScript turned off or an old version of Adobe's Flash Player."

Does this mean I need both JavaScript and the flash player?

What is the best way to install these and is there something else I might need/want to install in the future?

Thanks in advance. Bob.

Javascript is read by the browser. You can't install it.
You just need to download and install flash. It's in the repos as "flashplugin-nonfree" so run
sudo apt-get install flashplugin-nonfree

Thanks, that did the trick!
