Description

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.

Vendor	Product	Versions
Mozilla	Firefox	affected `unspecified - < 69`
Mozilla	Thunderbird	affected `unspecified - < 68.1` affected `unspecified - < 60.9`
Mozilla	Firefox ESR	affected `unspecified - < 60.9` affected `unspecified - < 68.1`
