The vote buttons are dead pictures and don't react, though the middle "show votes" still works. The flag and up buttons on comments are similarly affected, though they show up after touching the comment.
Is this just me? Is this a known issue? How do I make it work again? I'm running Firefox on Android, with "desktop" site (not the "mobile" view, which I don't like because the text is way too small)
Update: regular (non-beta) Firefox developed the same issue a few days ago. I suspect a bug in FF or irregularly in the site that bothers mobile FF, and the issue I saw in beta just moved to production.
So I uninstalled Firefox.
