Install Tampermonkey (a greasemonkey-like scripter for Chrome) http://tampermonkey.net/ and reinstall YTC through that.(Thanks Reddit) Now auto-play is disabled again, and the download drop-down is back on my Chrome.

My experience in downloading it yesterday was the FireFox user interface moved the "download" link to be on the left side with an orange "Download" appearing. Nothing like what is in the Know How video.

Ah derp. Firefox, not Chrome. I was having problems with the Chrome version, so for some reason I automatically assumed you were using Chrome. Well, if anyone's having problems getting it to run in Chrome, use Tampermonkey.

I found that version 2.1.0 from the Mozilla Add-on library did not give me a  download menu in YouTube. I downloaded version 2.1.1 from the github, installed it, and the download menu was present and worked (in Firefox)
