Javascript is not enabled according to a number of apps, including synch.

Question

I am informed by a number of apps (including FireFox Synch) that JavaScript is not enabled. I am running FireFox 33.0 on an ASUS tablet running Windows 8.1. I have re-downloaded and un/re-installed FireFox a number of times. These apps have run on other windows machines with no issues.

Answer 1

Interesting, when I go to the browser console, I get:
ReferenceError: chapters is not defined HTML.js:6
ReferenceError: version is not defined eASLRB.htm:71
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol. eASLRB.htm
The files eASLRB.htm, HTML.js, are in the folder in question. Never seen this before, but it sounds like a non-trivial error. Possibly a corruption of some sort when I copied from DropBox?
It looks like all the scripts being invoked are in a subfolder of the program folder nameded Scripts
