Unfortunately, this add-on is not doing anything at all for me in Firefox 65.0.2 on Windows7 64-bit. I like how it has options for both "autoplay" and "pre-loading" and that it is designed for all HTML5 video sites.

Other reports suggest that it works for some people, but not for others. Too bad, as the concept is useful and the interface is well-designed.

Ne fonctionne pas sur smallbusiness.chron.com avec Firefox ESR.

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 ...

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

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

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.

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.

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

Disappointing. Most of time it does not work.

Does not work at all.

Does nothing. Useless.

Version 2018.10.3 No longer works at all. Per-domain preferences always remains empty. No longer stops Youtube videos from playing.

Rolled back to Version 2017.12.20 which does work correctly. Remember to turn off Add-on auto update for this extension.

This adds is sock! Often sides use my CPU up to 100 percent. Its not in Windows, but also in Mac OS X

this breaks vimeo video playing.

I'm sure it worked before on Netflix (at some point) but after Netflix updates their site (which is quite often) this app no longer blocks autoplay content. I'm forced to remove this app and move on to something that works.

It doesn't work. Tried it on skysports.com & youtube.com and this extension didn't make any difference.

just useless doesnt work with youtube

Piece of garbage. Cannot enter exception sites like Hulu or HBO where I want AutoPlay On.

No response from the developer to my e-mail please for help.

DON'T WASTE YOUR TIME ON THIS TERRIBLE ADD ON

Used to be good, but now breaks vimeo (even when disabled) and causes high cpu load. Not recommended.

Downloaded twice but cannot find it among my Add-ons.
