As described here if you use the Chrome browser, install YouTube Options and specify the codec as Flash.
By default YouTube options will also change a bunch other aspects of the YouTube interface (e.g., hiding comments, video descriptions, ads, etc.). You may like this, but you may also want to modify some of this plugin behaviour if for example, you like ...

Right-click the video when it is playing or not and the context menu that pops up will tell you if you are using Adobe Flash Player or the YouTube HTML5 Video Player.
This is the right-click menu for the two cases:
In Firefox 36:

YouTube is changing the player from time to time, and they indeed removed the ability to like a video both in embeds and in full screen. There is no toggle or option or anything to bring it back, at least not via YouTube-native features.
I don't know the reasoning behind it, though if I had to guess it's because nobody used this feature, unlike the watch ...

Google Apps Script could be used to create forms, to add custom features to the Google Forms editor, to submit responses automatically and to do things on form submission but it could not add features to published forms like the embedding an HTML5 canvas.

Here is an extension that forces Flash on YouTube (tested on 02/05/2015).
Also, to remove the annoying fullscreen message type in the address bar: chrome://plugins/, find: "Adobe Flash Player" and check the box next to Always allowed.

I found a solution here: https://groups.google.com/forum/#!topic/mozilla.dev.extensions/0ZgKDAFfUDc
Here's how I disabled HTML5 video in Chrome on Windows:
Find the file called ffmpegsumo.dll where Chrome is installed (C:\Program Files (x86)\Google\Chrome\Application\30.xxxxx\ for me)

You can do this by changing the URL with any video.
Simply take the video id (like the KqnB2Ew0SFM above in the 1st answer
and add it after this: http://www.youtube.com/watch_popup?v=
(getting http://www.youtube.com/watch_popup?v=KqnB2Ew0SFM if using that video)
This way, the video takes up your whole screen and is forced to play in HTML5 (well, just ...

If you're willing to switch to Chrome, you can use this extension, which offers the option to force a certain player type.

The best advantage of HTML5 of YouTube player is compatibility with Android devices. When the user click the player to watch a video, no need to skip to YouTube App. Just embed and watch the video within the page, no Flash problems. At PresentationTube, we use HTML5 to allow mobile users watch the video within the page the same as the desktop.
