Short answer: No.
Long answer: Maybe. If you mean system environment variables, there isn't (that I'm aware of) any way to do that via straight JavaScript. You can access a number of system information through JavaScript though. Check this page out for some examples:
http://www.docsteve.com/DocSteve/Samples/JS/javascript_env.html
This shows how to get the underlying OS/platform, Depending on exactly what you're looking for, this may not work. It's possible via other methods, like creating an ActiveX object and using that. However, this requires additional steps on the user end (like installing/authorizing ActiveX).
I think this is a security feature, separating the system from the browser, therefore it can be difficult (or impossible, depending on your requirements).

Thanks for the help Josh. @Bears will eat you, you are right FF doenst support ActiveX, so I am out of luck here I guess
Josh
While FF doesn't natively support ActiveX, I've personally used ActiveX within FF before via an add-on. This was a while ago, 1.x, so maybe newer FF versions removed that capability.
