How to Disable a Pop-Up Blocker on Firefox

by Andrea ReuterUpdated September 28, 2017

The Mozilla Firefox browser includes a pop-up blocker that prevents websites from opening new windows without your permission. With the blocker enabled, you receive a notification from Firefox whenever a website tries to open a new window, and you're given the option to open the window manually or ignore it. Pop-up windows are integral to the function of some websites, like online gaming sites and financial institution websites, making it necessary to temporarily disable the Firefox pop-up blocker.

Select "Tools" from the top of your Firefox window.

Choose "Options" from the drop-down menu.

Select the "Content" tab.

Uncheck the box next to "Block pop-up windows" to disable this feature.

Press the "OK" button at the bottom of the "Options" window.


To enable the Firefox pop-up blocker to block new windows from some sites but not others, keep the "Block pop-up windows" feature checked and press the "Exceptions" button next to it. Enter the name of a website for which you'd like to permit pop-up windows and press the "Allow" button to add it to the list.
