Q:

Why is Chrome pausing on some line inside jQuery?

Every time I refresh my web app with the Chrome Inspector open it pauses and takes me to the sources tab with a big red arrow icon pointing to some weird line inside jQuery.
I see

Paused in debugger

in the top-middle of the window, and

Paused on exception: DOMException

in the Call Stack on the sources tab.
As far as I'm aware, I haven't set any breakpoints and this code wasn't throwing exceptions before - so what's going on?

A:

That little pause icon in the lower left.  Should be black in color.  Click it to cycle through several breakpoint options.

A:

I had been debugging and forgotten to remove a breakpoint. 

A:

Also check that you haven't ticked "Any XHR" under XHR Breakpoints.
