Description Mark Sadecki 2013-10-23 20:05:12 UTC
+++ This bug was initially created as a clone of Bug #10994 +++

Since accesskeys are chosen depending on the user's platform and available keys and available key bindings in the browser/OS, accesskeyLabel exposes that information about the user which was not possible before, i.e. it increases the fingerprinting.

Moreover, if a browser considers accesskeys from cross-origin iframes when assigning a key, accessKeyLabel exposes information about the cross-origin iframed document (if it uses accesskeys) which was not possible before, e.g. it might be possible to tell if the user is logged in on the other site.

We moved accessKeyLabel to WICG, since it had one buggy implementation and it would be nice if it were improved before we got more of them.
