Message Center Widget Blocker
This experimental Browser add-on prevents message-center-header-widget.js to load into cache pages and map.
I hope that this resolves freezing problems experienced by many Firefox and Chrome users, until the problem is solved by Groundspeak®.
When this add-on is running, the number of incoming messages will be updated only once and displayed in black colour as you see in the picture at top.
Message Center itself and some other pages does not use this widget, so there you will see ordinary white numbers updated in real time.
