Correct. Voting works, but the arrow icon will not update.

No, that's not true. Voting works properly, at least in my experience.

My current config: OS X, Firefox 45.0.2, NoScript 2.9.0.11.

What doesn't work properly is the search at the bottom of the page. For that I switch to Safari (with JS enabled).
