Can't Stop Autoplay

Post by swillson »

Firefox recently upgraded itself to version 63.0. Now videos play automatically (e.g., cbsnews.com).

No matter what I do, I can't get it to stop. Under Add-ons, I have Shockwave disabled. I also have Widevine disabled. The only other Add-on I have is OpenH264 Video Codec.

I went to (but did not change) about:config, looked up media.autoplay. Under media.autoplay.enabled it says "false".

Any suggestions?

media.autoplay.enabled
revert to default pls - this pref has a bad influence.

try
https://addons.mozilla.org/firefox/addo ... 2017.12.20

i suggest in special the previous build because comments said that current build is somehow broken.

Might read: https://www.ghacks.net/2018/09/21/firef ... -blocking/

Going to about:config and setting media.autoplay.default to 1 and setting media.autoplay.allow-muted to false will block autoplay everywhere. Same as using the now removed media.autoplay.enabled option.

Looks like there's not quite a UI front-end for this in 63 yet.

thats what i read some days ago
media.autoplay.default -> 2 for each site
media.autoplay.default -> 1 any site

media.autoplay.enabled.user-gestures-needed -> true for an (experimental) settings dialog

according to Sören Hentzschel media.autoplay.enabled is deprecated and no longer available
the magic number is 51 and you are probably part of it :p

The old media.autoplay.enabled preference has been replaced by several new ones as the feature is evolving from "all or nothing" to a site permission. Give this a try:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box above the list, type or paste autop and pause while the list is filtered

To set your preferred behavior:

Block autoplay by default

* Double-click the media.autoplay.default preference and set it to 1

=> Does that work for you?

Allow autoplay by default (default for Release)

* Double-click the media.autoplay.default preference and set it to 0 (or right-click > Reset)

Ask on a site-by-site basis (default for "Nightly")

* Double-click the media.autoplay.default preference and set it to 2
* Double-click the media.autoplay.ask-permission preference to switch the value from false to true
* Double-click the media.autoplay.enabled.user-gestures-needed preference to switch the value from false to true

I'm sure we'll learn more about the interaction of these various preference and what sites can bypass them as more users begin to run Firefox 63.

firefox 63 only has a simple checkbox, firefox 65 additonal offers a choice /seperate/all/never/ (and moved this dialog below, while 63 is upper)
