Ask HN: Is Voting Turned Off?

I was taking vacation from HN for a few weeks and some time ago I came back. I noticed the little triangles next to submission are gone, same for comments. Is this feature removed or something else happened that I'm not aware of (i.e. karma levels required for voting got higher). I googled for the answers but could not find explanation.

@version_five pointed out it might be my browser setup, indeed I see upvotes in a browser without addons installed. Thanks for hints!
