This has been a very common technique of tracking for a while. I doubt using a browser tab is even a novel use case.

Shocker

Is that why any tab (on Firefox) with aliexpress opened on it seems to always be showing that little loudspeaker icon at the top? There are a lot of products that have videos showcasing the product so at first I assumed it had something to do with that, but then I noticed it happens on products that only have photos, too.

As this is basically a PR campaign for Brave, here's your reminder to stop using that software:

They've been doing this for a very long time, and I was forced to stop using their website as a result. Nothing new here. If you're on Firefox, you can use an addon called JShelter to alert you when fingerprinting is taking place (and optionally block it).

I did some js reverse engineering work on chinese websites few years ago and it's legit industry leading tracking tech. Very few websites in the west are even remotely as sophisticated in that regard.

Unsurprisingly China has the best tracking ecosystem but it's not for the reasons you might think. It's just so competitive in China that tracking and automation blocking is super important for chinese businesses.

Have you noticed that there's no such thing like internet archive in China? It's because nobody wants it. It's too dangerous to have recorded history of any sort.

Firefox wouldn't let this happen btw. Just use firefox peoples

Cartoon villains envy their creativity.

The very few times I had to open AliExpress and give it wide permissions because otherwise it simply refuses to show anything - I always felt dirty afterwards.

It doesn't matter, I've never bought anything there.

holy fuck i am tired. everytime i read something like this is think "what kind of things do we not know about"

Is that on chrome or Firefox? I thought Firefox disabled media by default. Mine always requires a click to allow media.

Edit: maybe I changed the settings
