Navigation events were not fully adhering to the W3C’s “Navigation-Timing
Level 2” draft specification in some instances for the unload event, which
restricts access to detailed timing attributes to only be same-origin. This
resulted in potential cross-origin information exposure of history through
timing side-channel attacks. This vulnerability affects Firefox < 69,
Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR
< 68.1.
