Not able to open developer tools on a Modal dialog

Question

Not able to open developer tools on a Modal dialog in IE11 on windows 10. Recently I upgraded to Windows10, I have done the attached settings in my IE but still it is not working.

Answer 1

Open DevTools -> Console in the main window and run the following command:

window.showModalDialog = window.open

It will force browser to open all modal dialogs in a regular window.

Answer 2

Can you try running IE11 with add-ons disabled as this link suggests?

• Right-click on Start
• Left-click on Run
• In the Run dialog type iexplore.exe -extoff then click OK
• This opens IE with ad-ons disabled. Close the alert that pops up at bottom, the in the address bar enter a website to go to, then try press F12 again to see whether it opens properly. If it does, then you could open a normal Internet Explorer, and click Tools > Manage Add-ons and disable all you have then one by one enable them and test whether Developer Tool still works, to figure out which one is causing the issue.

The question seems to have been answered elsewhere. Interestingly asked by @vijaykandady on the other forum as well around the same date and marked as solved.
