> Issue: the autoplay doesn't work... may you help me ?
> Issue 2: why this video doesn't work on firefox ? (but work on chrome)
Hope someone knows the solution
Have a lovely day
See my response in this thread - Youtube widget autoplay function doesn't work which shall answer your query.
Also for enabling auto-play in Firefox refer this link - How can I disable auto-play for video content? | Firefox Support Forum | Mozilla Support.
Hope this helps.
Owing to how all modern browsers are disabling autoplay by default, your options are kind of slim. Don't expect it to work in every device. The goal is to protect users from unwanted data usage and excessive bandwidth consumption. According to Mozilla Developers Network, autoplay should be avoided.
