You don't need an extension for that. Go to about:config and set media.autoplay.enabled to false.

- nasredin 9y agoSpent a lot of time on this, so: NoScript ("allow first-party scripts" and block everything in "Embeddings" tab) + FlashBlock seem to be the only way to block all autoplaying crap in Firefox for me. You can also add uMatrix, uBlock & RequestPolicy and surprisingly they don't conflict with each other!
