Then repeat the whole process multiple times from loading the page.

Actual results:

The first time clicking OK or Cancel for each page load, the alert appears if Cancel was clicked and does not appear if OK was clicked. From the second time clicking OK or Cancel for the page load, the alert appears if OK was clicked and does not appear if Cancel was clicked.

Expected results:

Under all conditions, the alert should appear if OK was clicked and should not appear if Cancel was clicked.

This behavior reproduces on Desktop Firefox.

I can't reproduce this (using Nightly/Linux). What are the exact steps to reproduce.

The alert should be shown if the OK was clicked, and shouldn't be if Cancel was click, and that is the behavior I get.

Kevin, on which desktop platform did you see this?

I can't reproduce this on Windows 10 using nightly 71, either.
Going to close as WORKSFORME.

Kevin, please feel free to reopen when you have a chance to get back here with comment 4 and if it's still valid
