VistasReact dev tools - Deactivate "break on warnings"
While developing with create-react-app, my browser enters debugger mode on warnings:
It breaks on the source code of react-dev-tools:
// --- Welcome to debugging with React DevTools ---
// This debugger statement means that you've enabled the "break on warnings" feature.
// Use the browser's Call Stack panel to step out of this override function-
// to where the original warning or error was logged.
How can I deactivate this behavior?

It's a known issue. A workaround is posted on GitHub: Bug: Unexpected debugger statement in DevTools (solved) #19308

Go to your ReactDev tools in the tab Debugging and disable "Break on Warning".
I think this new behavior started today with this new PR: https://github.com/facebook/react/pull/19048

Based on pull request DevTools: Make break-on-warn off by default #19309 it seems it's a bug.
The Break On Warnings box was unchecked for me and it still would break. Removing and readding the extension to force an update fixed it for me.
I don't know of another way to force Chrome to update an extension outside of its regular schedule.

Go to Chrome Devtools → in the Chrome console, go to Component → Click on Settings → unset Break on Warning. Do the same in Profiler → Settings → unset Break on warning.
@cadoman pointed check and then uncheck to make work for sure.

The issue is due to a recent release. A Workaround proposed by the React team is:
- Go to Chrome Developer Tools
- Click on the Components Tab (React Developer Tools Extension)
- Click on the Settings icon (located next to the component search box)
- Once modal opens select the Debugging tab
- Finally, double click on the Break on Warnings checkbox (check and unchecked)
Make sure at last the Break on Warnings checkbox is unchecked.

Chrome has a "BlackBox script" feature which is useful in this case.
- Go to Chrome Developer tools -> source tab
- Select "react_developer_tools.js" from the left pane
- Right-click file and select "Blackbox script"
