Firefox blocks pop-up windows, but you can allow specific sites to create pop-up windows when needed.
Firefox blocks pop-up windows by default. When a website tries to launch a pop-up window, Firefox blocks it but also displays a warning. Click the warning to allow pop-up windows on that site.
To allow a pop-up window in Firefox, do the following:
- Launch Firefox.
- When you are on a website that attempts to launch a pop-up window, Firefox will block it and will display the following warning at the top of the page: "Firefox prevented this site from opening a pop-up window".
- Click the Options button on the warning message and do one of the following:
3a. Select Allow pop-ups for <site name> to allow all pop-up windows for the website you are currently visiting.
3b. Select Show <address> to allow the pop-up window to appear one time only. Future pop-up windows on the same site will continue to be blocked.
Pop-up windows are now allowed. If you are trying to access a website that uses pop-up windows, you may need to reload the page to allow the pop-up windows to appear.
