Bug Summary

The config media.block-autoplay-until-in-foreground in about:config is not working, whether set to TRUE or FALSE, it ignores the setting and thinks it's FALSE.

This very useful feature is working fine out of the box on Firefox ESR 128 and also Nightly 131.

Reproduction Steps

1. Install Floorp 11.17.5
2. Fetch https://www.youtube.com
3. Search for anything in order to get a list of videos
4. Right-click on any one in the list and open it in a background tab

Expected Behavior

The background tab should BLOCK autoplay, like this:

Actual Behavior

Instead, it plays the video:

Screenshots

In FF Nightly, as well as ESR 128, the same configs are set as in Floorp:

Except for Nightly, as well as ESR 128, the autoplay-until-in-foreground feature works.

Browser Version

11.17.5

Operating System

Arch Linux

Additional Context

• I have tried a numerous amount of configs and none made it work.
• I read this thread, but I cannot easily downgrade ffmpeg, as there are dependencies:
  
• I found one half-decent workaround, which is to Block Audio on the website, instead of Allow Audio&Video. This prevents background tab from autoplaying, but it does not autoplay when you bring it to foreground, you have to manually click either on the video or on the tiny PLAY button, depending on the website. This adds steps, time and multiply by the number of videos some people can load in background it adds up. Which is why it's only a half-decent workaround.

Since this is working with both FF ESR 128 and Nightly 131, I was wondering if something got impacted during the Floorp build process?

Wait, it doesn't work with ESR128?

[FGD-Garuda]

Wait, it doesn't work with ESR128?

Where did I write that? I will correct immediately.

It DOES work with ESR 128. You set it to TRUE and the Autoplay is blocked. You set it to FALSE and the Autoplay is not blocked.

Ah, I must have misunderstood “Except for Nightly, as well as ESR 128”.Sorry.

I believe this issue has been resolved. Please check the latest version

I believe this issue has been resolved. Please check the latest version

On v11.17.7 I have the exact same behavior as 11.17.5 from my OP, which is that specific config does take effect when set to TRUE (which is the default) and always behaves as FALSE.

Hi @surapunoyousei , since I don't seem to be alone with this behavior, is it possible to re-open this potential bug?

I don't think it gets a lot of attention being in the closed section.

Thanks

This prevents me from using the browser honestly.. I'm forced to stay with floorp-11.15 because of this, please fix it.. autoplay is unusable when everything starts playing in the background because you opened a couple of youtube tabs.. lol seems like an obvious thing to priority fix

this used to work fine, but i also noticed that it broke after the update. very frustrating to lose this functionality.
