Comments to articles broken in Firefox?

Is anybody else having a problem with comments not appearing after articles if you’re using Firefox? It doesn’t matter how I access an article (email link, TR page, other link), I can’t post comments, nor can I see comments that are already posted. One thing I have noticed is that the Profile indicator that usually sits at the far right end of the menu bar is missing on every page.

It’s not the whole site (I’m posting this question with FF), but any time I want to comment or read the comments on a posted article or gallery, I need to fire up IE or Chrome.

Specifics:
Windows 7 Home Premium (SP 1)
FF 48.0.2
AdBlock Plus (TR whitelisted)
NoScript (All scripts allowed)
