* This file contains a wrapper for [NetworkInformation](https://developer.mozilla.org/en-US/docs/Web/API/NetworkInformation#specifications).
|
|
* \ingroup wrappers
|
|
*
|
|
* NetworkInformation allows sites to learn about local network conditions by querying `navigator.connection`.
|
|
* Fingerprinters can misuse the feature. Long-term observers may learn about traveling patterns
|
|
* through observation of repeated values (for example a network at work, home, travel, etc.).
|
|
*
|
|
* We implement the same protection as Brave: https://github.com/brave/brave-browser/issues/20122.
|
|
*
|
|
* ```
|
|
* navigator.connection === undefined
|
|
* "connection" in window.navigator === false
|
|
* ```
