Ask HN: Why does Facebook.com activate the microphone?

14 points by 35mm 7 hours ago

In Safari on macOS when visiting the Facebook newsfeed, the system mic active icon appears in the menu bar and says that Safari is using it.

I haven't granted permission. When I asked ChatGPT it said 'Safari creates an audio capture session even if the user has not granted microphone permission, for capability negotiation, but no audio data leaves the device until permission is granted.' - is that accurate?

facebook is definitely listening. We have had many instances where wife and I discussed something and an ad appeared on fb related to that.

So it can listen to you and serve ads that track your every movement, word and thought like an uncanny evil genie?

Better question, why are you still on facebook?

“Oh, Grandma, what big ears you have!”

“The better to hear you with, my child,” came the growling reply.

That's odd. ChatGPT (5.1) tells me Safari does not open an audio capture session for 'capability negotiation' that would show the mic icon.

I assume you have Safari > Settings > Websites > Microphone > facebook.com set to the default "Ask", or to "Deny"? Also check any installed extensions.
