stop video autoplay
the only autoplay setting i can find is under privacy and security. the page shows DEFAULT FOR ALL WEBSITES: Block Audio and Video, but videos still open and play. the page does not retain the change when i select the button REMOVE ALL WEBSITES. this problem has not been happening for years. it may have begun about six months ago. thank you for your time

Hello
Maybe ? take a look at https://connect.mozilla.org/t5/discussions/firefox-dont-block-video-play-even-if-autoplay-is-prohibited/m-p/57558
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".
will these about config amendments survive updates?
