You can look at these prefs in about:config to see what settings work for you to block media auto-play.

• media.autoplay.default = 5 [0:allow;1:blockAudible;5:blockAll]
• media.autoplay.blocking_policy = 2
• media.autoplay.allow-extension-background-pages => false
• media.autoplay.block-event.enabled => true
• media.block-autoplay-until-in-foreground

You can open about:config via the address/location bar. You can read the warning and click "Accept the Risk and Continue".

cor-el. You obviously didn't read my post. I clearly wrote "NONE work with yahoo." I use v133.0 FF

Example video would be nice. What version of Firefox? What OS?
