Hello, The option "disable the automatic playback of video" is checked but do not work. Videos continue to start automatically. I don't understand why... I have FF 66.0.2 on my Redmi 4x / Android version: 7.1.2 / MIUI version: Global 10.1.1.0 Any idea to solve the problem? Thanks a lot. L.

Can you provide a website address, where to find this video?

I have this problem with several websites, for exemple (i'm a french user): https://m.lequipe.fr -> https://m.lequipe.fr/Football/Actualites/Ligue-1-5-choses-a-retenir-de-lille-psg/1009477 https://www.ledauphine.com

On about:config i have media.autoplay.enabled false

Can't reproduce. Videos are unavailable in my country.

What a shame... Maybe I would have to find a website in .com ?

For information, in about:config, I have tested all "autoplay" settings on "disable", but it did not solve the problem...

Have you any idea for others tests ? Thx.

I'm seeing videos autoplay now on mobile.twitter.com when I scroll down, despite the fact that I selected "Block autoplay" in advanced settings and set media.autoplay.default to 1 in about:config.

Twitter seems to have found a way around FF's user preferences, or else there's a bug in FF 68.0.2.
