User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20180103231032 Steps to reproduce: 1. in about:config set media:autoplay:enabled to false 2. Open netflix.com and choose a video Actual results: Video won't play Expected results: I expect that media controller will show to play video.

This is old problem like Vimeo's one, it's solved if the pref "media.autoplay.enabled.user-gestures-needed=true". We won't maintain the old pref with "media.autoplay.enabled.user-gestures-needed=false" anymore.

What is a user supposed to do exactly to achieve this: 1. Don't autoplay the videos on the web (like abc news, youtube etc.) 2. Have a working netflix If I set both media.autoplay.enabled=true and media.autoplay.enabled.user-gestures-needed=true, 2. works but videos on websites play automatically, which is very annoying. If I set media.autoplay.enabled=false, netflix does not work but 1. works fine. Please help.

We're implementing a third option for blocking autoplay of audible videos which I hope will address your issue. It's not ready yet, but should be available later this year.

But this was working in FF57. I had media.autoplay.enabled=false and both 1. and 2. above were working fine. What changed in FF58 to cause this regression? Is there no way to achieve the behaviour of FF57 in FF58?

BTW, I don't really care about the audible or not, I just don't want the videos to play. They are annoying and suck up battery. Its one of the biggest complaints I have with other browsers.

The solution is to allow users to white list sites. so a global auto-play function that I can turn off for the entire web, then a white list of sites I enable autoplay for. Let this sync in my profile so it applies to all my devices with firefox on.

Quoting Sunil "What changed in FF58 to cause this regression?" ... Can anybody answer that?
