Mozilla Says Chrome’s Latest Feature Enables Surveillance

Chrome 94 has officially dropped. As is always the case with a new browser 
version, there’s plenty to be excited about.

However, there are also some items to be skeptical about, including a feature 
Mozilla claims enables surveillance on you.

How Chrome’s New Feature Is “Harmful”

Chrome 94 introduces a controversial idle detection API. Basically, websites 
can ask Chrome to report when a user with a web page open is idle on their 
device.

It’s not just about your usage of Chrome or a particular website: If you’ve 
stepped away from your computer and aren’t using any applications, Chrome can 
tell the website you’re not actively using your computer.

As you might expect, developers love this new feature—anything that can provide 
them with more information regarding how users are interacting with their apps 
is a positive.

It’s enabled by default in Chrome 94, but it might not be as bad as it sounds. 
Like using your webcam or microphone, a prompt will ask your permission before 
using your idle data on a particular website.

The API comes with its fair share of opponents, including rival browser-maker 
Mozilla.

The folks behind Firefox say that it creates an “opportunity for surveillance 
capitalism.”

Mozilla’s Web Standards Lead Tantek Çelik commented on GitHub, saying:  As it 
is currently specified, I consider the Idle Detection API too tempting of an 
opportunity for surveillance capitalism motivated websites to invade an aspect 
of the user’s physical privacy, keep longterm records of physical user 
behaviors, discerning daily rhythms (e.g. lunchtime), and using that for 
proactive psychological manipulation (e.g. hunger, emotion, choice)…

Thus I propose labeling this API harmful, and encourage further incubation, 
perhaps reconsidering simpler, less-invasive alternative approaches to solve 
the motivating use-cases.

Of course, Mozilla competes with Google Chrome, so it’s not surprising that a 
competitor might have strong words about something Google is doing.

However, it isn’t just Mozilla. Apple’s Safari browser uses WebKit, and the 
WebKit development team also had a lot to say about the new API.

Here’s what Ryosuke Niwa, an Apple software engineer who works on WebKit said: 
“That doesn’t seem like a strong enough use case for this API. For starters, 
there is no guarantee that the user won’t immediately come back to the device. 
Also, who is such a service supposed to know what other device user might be 
using at any given point? We’re definitely not going to let a website know all 
the devices a given user might be using at any given point. That’s a very 
serious breach of the said user’s privacy. It seems to me that such a 
suppression / distribution mechanism is best left for the underlying operating 
systems / web browsers to handle.

We’ll have to wait and see how developers use this new API in Chrome. It could 
end being an absolute privacy nightmare—or it could be no big deal.

And, either way, it’s worth remembering that websites can’t get notified of 
your idle status unless they ask you first and you agree to share it.

Either way, there’s some good stuff coming in Google Chrome 94, and it’s worth 
downloading for just the security fixes alone.
