Firefox enables the use of JavaScript by default. Are you using extensions which block JavaScript?

There is an excellent Mozilla support article about JavaScript settings and preferences for interactive web pages: http://mzl.la/1BAQTqA

Your System Details shows the NoScript extension and this extension block by default all JavaScript. You are supposed to unblock essential JS files to make a website work or you need to disable NoScript on websites that do not work properly.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
