No video, audio continues Rated 2 out of 5 stars

The idea is great. Video doesn't play. Audio starts playing.

Works perfectly in this house Rated 5 out of 5 stars

I enjoy to watch 3D movies on the You Tube, but the cursed HTML5 it turns out was preventing any "options" so was forced to see only side by side vs coloured glasses. With this add-on, the various 3D options are fully restored! That's excellent. tx

Simple and effective Rated 5 out of 5 stars

All I wanted is something that stops youtube videos from automatically playing. Everything else glitches or doesn't do what it says. This is simple and effective. It should get more stars than what it has on average.

Stops autoplay but manual play doesn't work either now Rated 1 out of 5 stars

Firefox 40.0.3 running on Win 10 Pro and Flash is not installed. The basic function works where the autoplayed HTML5 video is replaced with a click-to-play link. However, when I try to manually start the video, the video errors (An error occurred. Please try again later.) while the audio plays correctly.

Youtube still tries Flash Rated 3 out of 5 stars

I see the click-to-play screen for half a second, then Youtube tries to play the flash version. So I have the same situation as with noscript: I can stop autoplay, but if I want to actually play a video, it's always flash.
I am logged in to Youtube and I have set the html5-option. (Firefox 40.0.3, Ubuntu 14.04)

I does not work. Autoplay continues

Fantastic workaround for ubuntu/firefox/html5 disable Rated 5 out of 5 stars

This is the only workaround for ubuntu 14.04 with FF 40.0 and buggy html5 playback, so I can use Flash until bugs are solved.
Thank you.

Works ok but only for fresh page loads and not refresh or links.

BROKEN. It does stop the video from autoplay but it also stops it from ever playing at all. Even when you click on the play button or logo now the Youtube video won't load!
It's useless!

don't playing

It doesnt work Rated 1 out of 5 stars

The trick with "media.windows-media-foundation.enabled" setting to false, also doesn't work. It forces flash player and so this addon is effectively useless.

Useless. All it does is cover the video with an overlay while the video continues to run behind it.

In order to make this work again following needs to be set to false

media.windows-media-foundation.enabled;false

in about:config

Gives error message and won't let the video play Rated 1 out of 5 stars

For a couple of weeks the add-on worked fine, but now on some videos's on YouTube a error message: Click To Play appears. when you do the video won't play! On a other video the audio plays fine but the page with the upload won't show up!

Not on 36 it doesn't Rated 1 out of 5 stars

Doesn't work on current Firefox 36. I hear the audio playing and the video seems to be streaming, but invisible. Clicking restores video without delay, reinforcing the feeling the video was playing anyway and was hidden.
