Description

In several places the browser UI did not correctly distinguish between true user events, such as mouse clicks or keystrokes, and synthetic events genenerated by web content. The problems ranged from minor annoyances like switching tabs or entering full-screen mode, to a variant on MFSA 2005-34

Synthetic events are now prevented from reaching the browser UI entirely rather than depend on each potentially spoofed function to protect itself from untrusted events.
