I conect to a website to enter data into a package. Part of this is a lookup to find a unique reference for a property by entering PostCode and house number into a dialog. Fire fox will no longer open the dialog and displays message "Firefox prevented a popup opening". How can I allow popup on this website or globally?

Don't you see a pop-up block icon at the right end of the location/address bar?

You can inspect and manage permissions for the domain in the currently selected tab via these steps:

  • click the "Site Identity Button" (globe/padlock) at the left end of the location/address bar
  • click the arrow to expand the security message
  • click "More Information" to open "Tools > Page Info"
  • click "Permissions" to inspect and modify permissions

Alternatively go to the Permissions tab (right-click web page: "View Page Info" or Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab.
