Can websites see my device information or the serial number of the PC / laptop?

As already described, I ask myself whether websites are able to view my device information of my PC / laptop or even the serial number. Or. What can websites generally see and how does that relate to data protection?

Usually yes. I don't know the serial number, but device information such as battery, location, device name, Wi-Fi network, yes.

Yes, for example via canvas elements. Whereby not the serial number. However, information about the components is transmitted from the device. In combination with the other information (IP address, browser, operating system, etc.), a device can be identified almost clearly.

The best way to protect yourself from this is to use Firefox. Firefox is the browser for people with a need for privacy. Such methods are automatically blocked there.
