Hi, try the setting on the Options page mentioned in the following article: Allow or block media autoplay in Firefox.

Note that Firefox's feature only applies on the initial load of the page, so you are right that you also need to turn off YouTube's feature to continue down its playlist after the first video.

Thanks for the prompt response. I have enabled blocking in Otpions and it did no good. As temporary fix I found an extension called Play that will work for now. It might be helpful to have all the correct values in about:config for "autoplay" search. Where can I get them for v66?

You can search other recent threads. Users disagree on the best combination.

You can look at these prefs on the about:config page to see if these values work for you.

• media.autoplay.default = 1 [0=Allowed, 1=Blocked, 2=Prompt]
• media.autoplay.allow-muted = false
• media.autoplay.enabled.user-gestures-needed = false

For user-gestures-needed you can try false and true to see what works for you. You can look at this extension.

• Disable HTML5 Autoplay https://addons.mozilla.org/firefox/addon/disable-autoplay/

when searching the forum it would help to have a timeframe and a subject to search. when did v66 come out? what's the best search verbiage? thanks.

thanks, cor-el.
