I'm thrilled to say that, to date, this works exactly as described--including Youtube videos. What a relief. While it would be very nice to have a whitelist, I have not found it too distracting to have to click once to get a video started.

I actually love your addon (I should have rated it 5 stars). The problem I have is that it's actually breaking a site that I go to heavily -- (https://www.wowhead.com). I've unchecked the site from the icon, yet the settings information does not list that the site was excluded. Actually I can't find a way to manually exclude (type in the actual url of the site) this addon from working on a particular site. This addon works like a dream to prevent sites that I visit from auto loading video. I just wish that I could keep it from working on other sites that I visit. (ie the check - uncheck boxes are not working) {{{Win 10, Firefox 64.0.2}}}

It conflicts with the PayU form. When you try to enter anything, the form disappears. Because I have 30 plugins, finding a guilty little pissed off. I've lost a lot of time. And the plugin works on average, especially on YouTube. Thank you, but no longer ...

This add-on only half works. It works for other sites that use HTML5 video but NOT YouTube.

I installed DHA but it does not stop ANNOYING HTML5 videos on Yahoo from auto starting!

Или работает, или нет. 50%

Marche très bien, very good ! Thanks you.

This add-on, unfortunately, does not work for me.

Add on is working great, however it would be better if the videos(particularly embedded youtube ones) don't buffer in background.

This plugin not only didn't work for me, it interfered with the functioning of my password manager (LastPass) so that I wasn't able to log into it, or to access remembered passwords for sites where the password screen was separate from the user ID screen. I am on Windows 7, and I am running a lot of other FireFox extensions.

doesn't work at all.

Does not work at all. Rubbish.

WORKS FINE in Firefox on my Win10 computer and in Firefox Beta on my LG Android phone. I don't know why people give it such a bad rating.

as of 11/12/18 the addon does not work. If your on the latest version of FF, best option is to go to about:config, at the top search for autop, find media.autoplay.default, and change from 0 to 1 by right clicking the entry, and choose modify.

extension seems broken. Just won't work.

NOT WORKING AFTER UPDATE.PLEASE FIX

FINALLY this worked. The prior attempts to disable website audio autoplay via about:config settings only worked on my devices, but not my desktop. This plugin did the trick and eliminating a regular source of irritation. Thanks, Afnan!

the best solution :

in about:config you can set media.autoplay.default to 1 in order to block automatic playback on all pages or set it to 2 to decide on a per domain basis.

Worked for a few days, now doesn't do anything anymore. Became useless.
