The NoScript comment is because that is the "killer app" for Firefox for me, and on mobile Firefox it is not available. There's the amusingly titled "NSA" addition - http://noscript.net/nsa/ - but as you can see from that page it is pretty much dead. A forum post from November 2013 (1) indicates that the author is aware of the problem, but the diverging code bases I guess make it difficult to maintain.
