Blocks videos successfully, but exceptions list does not work. HTML standards bodies need to come up with a real option for disabling autoplay instead of these half-baked, buggy solutions.

It works, but stopped video cannot resume.

Works with YouTube perfectly as well as any other site using HTML5.

It works great! Finally I have a way to prevent youtube videos from automatically playing. A bunch of addons that specifically say that they'll stop youtube from autoplaying don't work at all. Thank you so much for this addon.

Edit: Idk why a bunch of other comments are so negative when all the other addons I've tried are the "piece of garbage" addons.

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

Works great!
Feature for deserving 5 stars: allow to edit/add whitelist items.
As of v2017-12-20 it has to be enabled for every bandcamp.com subdomain (anydj.bandcamp.com)

Could you please implement a fix for that?

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

Vielen Dank für das Addon. Genau was ich gesucht habe. Autoplay wird überall blockiert und auf Seiten wo ich es doch haben will (Yotube) kann ich es gezielt einschalten. Keine Probleme :)

Works on gazeta.pl

This add-on is an excellent add-on. It works flawlessly. Do try.

Works more often than not, but has misses. I think maybe it generally fails when the video is in an iframe. Looks like embedded YouTube videos always play automatically. Used to work against the very annoying BBC video preview but seems not to work anymore.

Works nicely. Blocks annoying videos from playing automatically when a page loads. If you want to see an example of an annoying video, check out Texas A&M's homepage: Without the extension (or with it disabled), you have to tolerate a full-screen background video of people walking through campus and a large flag, flowers, foliage and other stuff blowing in the breeze for what seems like an eternity. With the extension enabled, the first image is stopped in its tracks and the extension allows you to get down to the business of finding your way around the site. This extension allows the user to decide when to play a video, rather than leaving it to the whims of a website developer.

Love that it stops auto-play on sites that I've never visited before. Was very easy to allow Youtube to automatically play while everything else doesn't.

Can cause high 100% processor (cpu) usage, browser freeze, overheating, memory (ram) leaks on random pages.

Completely blocks video on vimeo.com

Developer does not respond to emails.

recently vimeo videos don't play with this addon enabled, even with selecting not to disable auto-play and preloading

The first one I've tried that actually works!! Well since the old flash days that is. It actually blocks HTML5 video, transforming my browsing experience. Thank you so much.

Super w 100% polecam w końcu mogę ustawić przeglądarkę tak jak Ja sobie życzę, np blokowanie autoplay na onecie, a na youtube startuje. Nie ma też żadnych problemów z pracą działa tak jak powinno !!!!

This solved the problem pronto! And with no apparent "side-effects" on my system or on the websites.
