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?

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