Sadly It BREAKS with Vimeo even if disable autoplay and disable preloading are off by default. Please fix it. Otherwise very useful.

Only works if I disable preload. I want it to preload I just do not want it to auto run. So it's partially broken and unusable for me.

Works well for what it does. Desperately needs a way to manually add domains though. For example, I can allow old.reddit.com and www.reddit.com, but video is still blocked because it comes from v.reddit.com…

Because you can't manually add a domain, even if you know what it is, you have to figure out a way to unembed the movie so you can play it as a standalone URL and *then* allow video to autoplay from it.

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.

Installing this extension into 163 mailboxes is a blank page. Prohibit expansion can be normal!

On vimeo, this app prevented me from seeing or playing any videos. I like the idea, but I do need to see the videos to play them.

The white list doesn't work correctly. Doesn't block autoplay videos on NFL.com which was the whole reason I installed it.

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 works but it breaks Vimeo (black screen instead of video playing).

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
