When debugging in chrome, the scripts are always paused in the debugger even if there are no break points set, and if the the pause is un-paused, it again pauses itself.
Really silly issue that I ran into that led me here with the debugger; command.: "debugger;" has a watch set on it.
It caused a page that just said debugger; to appear between every page load.
The way to disable it is to just right-click said Watch and click "Delete watch expression".
