Some websites use browser pop-up windows for certain functions. Those pop-ups can be blocked by your browser's pop-up blocker, which may cause issues on the site.
The easiest way to resolve this issue can be temporarily turning off the pop-up blocker. You can turn the pop-up blocker for your specific browser on and off by following the instructions below.
It is highly recommended that you turn your pop-up blocker back on after you have accessed the content that you need. All of these browsers allow you to specify which websites are allowed to open pop-up windows, which is a much safer web browsing option.
