With version 14 of the popular Firefox Browser the camera view thumb nails flicker in MJPEG and Script Stream Mode. This behavior looks like a bug in Firefox 14 on Mac.
We released an update for version 3.74 to display a proper video streaming in the thumb nails. Please update your C-MOR Video Surveillance if you use a Mac computer and when you experience this problem.
