Re-enabling window.alert in Chrome

I can see that this only for actually turning the dialogs back on. But if you are a web dev and you would like to see a way to possibly have some form of notification when these are off...in the case that you are using native alerts/confirms for validation or whatever.

Close and re-open the tab. That should do the trick.

In Chrome Browser go to setting , clear browsing history and then reload the page
