Fixed In Version: firefox 68.2, thunderbird 68.2
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in Mozilla's firefox and thunderbird where if two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This could cause an interaction between two different sites on two different windows running under the same application.
