MouseZoom damaged Puntuado con 3 de 5 estrellas
my FireFox. By accident I doubleclicked the MouseZoom statusbar symbol. This done, almost the complete inner window of Firefox was gone, just the titlebar and the window-backgound was left over (no content area, no toolbars nothing else). Closing the remaining frame and restarting FireFox restored the browser. I am still using your extension, but I edited mousezoom.xul and removed "mousezoom.toggleAFS();" - still don't know what its for.
Hope you may be able to fix it.
