hi, in firefox 63 the autoplay preferences are reorganised in preparation for this feature shipping out of the box in one of the upcoming versions. until then in about:config you can set 'media.autoplay.default' to 1 in order to block automatic playback on all pages or set it to 2 to decide on a per domain basis now.

Video from dailymail.co.uk still plays automatically with auto play setting at 1 e.g. the Green video.

The same page does not auto play in 62.0.3.

Config settings- search about:config autoplay values = false,false,true,true,true,1,false,true,true

hi, i think i cannot reproduce that on the main dailymail.co.uk site (i have no video that's playing when media.autoplay.default is set to 1). in case this is happening in a particular article, can you please post the exact link and/or a screenshot for clarification.

>Config settings- search about:config autoplay values = false,false,true,true,true,1,false,true,true
same goes for your settings, can you please provide a screenshot (i only have 8 preferences; values will depend on sorting order etc...).

can you try to reset all bold autoplay  preferences with a right click and then just set media.autoplay.default to 1?

"can you try to reset all bold autoplay  preferences with a right click and then just set media.autoplay.default to 1?"

The above seems to have worked.

Settings before reset to default were

media.autoplay.

allow-extension-background-pages false
allow-muted false
ask-permission true
block.event.enabled true
block-webaudio true
default 1
enabled false
enabled.user-gestures-needed true

media.block-autoplay-until-in foreground true


As an aside I cannot see how to attach a screen shot to bugzilla hence the re typing.

Update 

My Ubuntu machine updated yesterday and had the same problem - some videos autoplay.

The setting media.autoplay.enabled;false appears to be the issue.

The media.autoplay.enabled;false setting carried over from 62.0.3 and with this set media.autoplay.default;1 in 63.0 appears to be being ignored.

Changed media.autoplay.enabled;false to the default which was string and problem solved - no auto play so far on the test site.

Many thanks to all for the quick feedback.
