Mozilla developer Boris Zbarsky reported an inconsistency with the different JavaScript engines in how JavaScript native getters on window objects are handled by these engines. This inconsistency can lead to different behaviors in JavaScript code, allowing for a potential security issue with window handling by bypassing of some security checks.
