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.

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.

Seems to work fine for me, don't wanna live without it.

Very nice addon, seems to block most things although some fly under the radar. I would like to be able to add a wildcard. On bandcamp.com, each band has their own subdomain, so you have to add band1.bandcamp.com, band2.bandcamp.com, etc. It would be nice to be able to manually add *.bandcamp.com

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

It works on script clicking pause button. Very often it goes into loop and uses 100% CPU.

Per-site whitelisting is great

The pre-loading option so needs to go bye-bye.


6/8/18 EDIT: Eh, forget what I said. The add-on just needs to be updated.

Working great!

Simply doesn't work. Installed it and went to some sites I knew did autoplay video to test and they continued to do so, even after restarting Firefox.
