>> I upvoted this submission, but I don't see any unvote link anywhere (I even refreshed the page and am currently logged in). Am on Firefox 35.0.1 (if it matters).

I just read a comment in this thread that the unvote link lasts for an hour. I don't recollect if I actually voted an hour before I started looking for the unvote link. I didn't start looking for it immediately after I voted this up, so it's likely that an hour had passed.
