|
|
* `window.name` provides a simple cross-origin tracking method of the same tab:
|
|
*
|
|
* ```js
|
|
* window.name = "8pdRoEaQCpsjtC8w07dOy7xwXjXrHDyxxmPWBUxQKrh7xfJ4SYFH8QClp6U9T+Ypa8IEa5AwFw3x"
|
|
* ```
|
|
*
|
|
* Go to completely different web site and window.name stays the same.
|
|
*
|
|
* \see https://2019.www.torproject.org/projects/torbrowser/design/ provides a library build on
|
|
* top of `window.name`: https://www.thomasfrank.se/sessionvars.html.
|
|
*
|
|
* \see https://html.spec.whatwg.org/#history-traversal; this feature should not be ncessary
|
|
* for Firefox 86 or newer https://bugzilla.mozilla.org/show_bug.cgi?id=444222.
