Firefox hangs ReactOS if maximized (r68908)

Firefox version 24b hangs ROS if maximized. This also seems to destroy the saved profile settings as starting firefox again causes several asserts.
Unfortunately, the logs dont show anything when the hang occurs.

Assert example:
Entered debugger on embedded INT3 at 0x0008:0x809647e2.
