Frequently asked questions
Q: When I click on the Download button, there is no menu. What's going on?
A: This occurs when an error causes the script to crash. This can be caused by any number of problems, ranging from YouTube updates, to incompatible extensions or userscripts. Make sure you're running the latest version of your browser, the latest version of the script and the latest version of Greasemonkey (if applicable) and tell me about the problem so I can fix it.
Q: I thought you said this script could download videos in 1080p. Why can't I see a 1080p download link?
A: Not every format is available for every video. For example, 1080p (Full HD) downloads are only available for videos that were originally uploaded in HD and were uploaded recently. This is because of the way YouTube encodes and stores videos. To test a 1080p download, try this video: http://www.youtube.com/watch?v=9dgSa4wmMzk.
If you find a video that this script can't download in any format, please tell me about it.
