Google chrome not displaying alert() popups for one site

Question

I was working on a javascript loop that alerted each key value as the loop progressed.

To speed things along, I checked the box \"Prevent this page from creating additio

Answer 1

Restart the browser, that should reset that option and show you new dialog boxes.

Answer 2

You don't need to restart the browser. Just close the tab and reopen it again. It does not need to be Incognito.

Answer 3

FROM THE OP:

The solution was to restart the browser. Lose all my tabs? No!!!

However, there's a way to restart your browser and not lose all your tabs.

Install the Session Manager add-on. There is a version of Session Manager for both Chrome and for Firefox.

Session Manager maintains a running list of your open tabs and will automatically ask you if you want to re-open them ("recover your session") after an unexpected reboot or system crash.

Additionally, Session Manager will let you save your tabs on demand and reload them at a later time, or after a reboot. You can save your "session" (all open tabs) any time you want, and give the session whatever name you want.

Finally, when reloading a previous session, you can also choose which tabs to re-open and which tabs to ignore.

Can't live without it, in either Chrome or Firefox.

Chrome extension

Firefox extension

And if you are using IE . . . well, you have other problems.

Answer 4

Roberto's answer regarding the placement of the script command before the end of body worked for me. I had spent hours trying to figure out why my console command was not working.

Answer 5

If you want to detect if these are being blocked. You will have to do your own thing with the message you will be dispalying but override the native alert/confirm.

window.nativeAlert = window.alert;
window.alert = function (message) {
var timeBefore = new Date();
var confirmBool = nativeAlert(message);
var timeAfter = new Date();
if ((timeAfter - timeBefore) < 350) {
    MySpecialDialog("You have alerts turned off, turn them back on or die!!!");
  }
}

window.nativeConfirm = window.confirm;
window.confirm = function (message) {
var timeBefore = new Date();
var confirmBool = nativeConfirm(message);
var timeAfter = new Date();
if ((timeAfter - timeBefore) < 350) {
    MySpecialDialog("You have alerts turned off, turn them back on or die!!!");
}
 return confirmBool;
}

Obviously I have set the time to 3.5 milliseconds. But after some testing we were only able to click or close the dialogs in about 5 milliseconds plus

Answer 6

Not tested but if you have the problem again I think opening the site in an incognito window will reset the dialogs.

Edit: I added this answer which worked for the Chrome build as it was. Updates might have rendered this unnecessary (appreciate not to be marked down!)
