Bug 139542 – Web Inspector: Add toggles for debugger pauses at console.assert failures

• Component: Web Inspector
• Status: RESOLVED FIXED

[Brian Burg]

The debugger; statement will always pause if the inspector is open. It would be nice to have a toggle for that.

Perhaps we need two sections: one for "Debugger Pause Options" and another for "Breakpoints" ?

[Joseph Pecoraro]

I agree. We overload "Pause on All Exceptions" to mean a lot. Currently it:

  - pauses on console.assert failures
  - pauses on CSP (Content Security Policy) violations

These distinct issues could be pulled out to be their own toggles alongside a toggle for "debugger" statements.

Something else to keep in mind. DOMDebugger events still need a place to go:

  - pause on DOM events (click, touch, mouse, key, input, orientation, geolocation, ...)
  - pause on DOM errors (XHR failure, WebSQL errors, IndexedDB error)
  - pause on Promise lifetimes (rejection, resolved/fulfilled)

I was getting sick of pausing at assertion failures so I added a global breakpoint for Assertion Failures.

Cool!

This makes me wonder if we should drop "All" here. It looks funny next to "Assertion Failures" that does not have "All".

I agree. I'll rename it "Uncaught Exceptions" when I land.
