Format labels are now included in the download links
Recently, I found that the thumbnails were not loading and the alternative download links were not getting listed. Both problems have been fixed in this update.
About this User JS
Disables ads, turns off autoload/autoplay, adds RSS link, deletes “recommended for you” videos, unhides description, displays all comments, changes profile link to videos page; changes region to US, displays video thumbnail image, and adds a link to the lighter version on Hooktube if video is not playable for codec reasons. Supports Firefox-based browser up to Firefox 36. Newer versions should use a UserAgent (UA) spoofer add-on. YouTube loads a lighter version of the YouTube page for older browsers. This script will require the GreaseMonkey add-on to be executed by the Firefox browser. For embedded YouTube videos, use the script com.vsubhash.js.embedded-video-catcher.user.js.
The download links can then be sent to the DownThemAll add-on with the file renaming mask set to “*text*.mp4”.
