Firefox 66 still auto-plays videos

Posted

I'm on Linux, and updated to Firefox 66 yesterday. I was looking forward to the new feature that disallows websites auto-playing videos. But I found that it's not the case. For example, https://www.bloomberg.com/news/articles/2019-03-19/how-an-extra-man-in-cockpit-saved-a-737-max-that-later-crashed still starts playing the video automatically. This is just one of the many I've tried so far.

Am I missing any settings? There was none I could find having done a quick search on the preference page.

Chosen solution

With these pref settings on the about:config page auto=play should be disabled.

  • media.autoplay.default = 1
  • media.autoplay.allow-muted = false
  • media.autoplay.enabled.user-gestures-needed = true

Hello jeenuv and badbanana,

Would you please take a look at these release notes :

See what's new in Firefox

When you scroll down to "new" you will see this :

"Firefox now prevents websites from automatically playing sound. You can add individual sites to an exceptions list or turn blocking off. To learn more about block autoplay, which will be rolled out gradually to all users, visit the Mozilla blog."

Now that you point out, I notice rolled out the part. The announcement gave the impression that it's ready to go.

So we are to expect 66.* versions soon, then?

May or may not be in a 66.0.# 'chemspill' release, but IMO if that is done it wouldn't be for that feature alone - more than likely packaged with other 'necessary fixes' that would affect security or major breakage with other features. I base my opinion on how the "Form Autofill" feature was "rolled out" slowly - but that was a "system extension", so my guess may not be accurate.

In about:config you may want to take a look at the prefs that begin with - media.autoplay. - and see what is and isn't enabled. IMO that is where the "roll out" will tinker with the settings or features. Overall, my guess is that the next full version is where the "roll out" will continue ...

This update seems to be about setting media.autoplay.default = 1 to block autoplay by default, so you will get a special icon at the left end of the location/address bar.

To make the "stop autoplay" work again use these settings:

media.autoplay.default: 1 media.autoplay.enabled.user-gestures-needed: false media.autoplay.allow-muted: false

Although the "media.autoplay.enabled.user-gestures-needed" seems to be wrong it brings back the "stop autoplay" feature.

Tried all the manual fixes to stop autoplay, these fixes worked in 65.2 but not in 66.0 so until Mozilla fully releases the autoplay stop option I suggest re-installing 65.2 like I did, no autoplay now and I am a happy camper again.

Tried that but for some reason videos still autoplayed, I re-installed 65.0.2 and the settings worked for me. It's a crap shoot as to what will work for your particular system, I'll wait for the 67.0 update and see if it blocks autoplay.

Please STOP posting and reposting the "about:config" instructions. THEY DO NOT WORK. I'm sick of seeing this repeated again and again and again.
