Hi guys,

With previous versions of Firefox I have had it muted in the mixer and this has been ok for those websites which autoplay video.

Since upgrading to 57.0, where Firefox runs on multiple processes, this no longer works as it has multiple mixer tabs.

Is there any way I could fix this and have all firefox tabs start muted? is there an about:config option?

Cheers, Andrew
