Mozilla Firefox is a popular web browser and one of the most popular browsers in use today. It’s also one of the most popular browsers in history, with over 1 billion active users. One of the features that makes Firefox so popular is its ability to disable pop-ups. Pop-ups are small, annoying ads that show up on your screen when you visit websites or apps. They can be a nuisance because they can slow down your browsing experience and make it difficult to do your work. To disable pop-ups in Mozilla Firefox, you first need to open Mozilla Firefox and click on the three lines in the top left corner of the window. This will open a menu where you can select “Options.” In this menu, you’ll find “Privacy.” In this section, you’ll need to select “Disable Pop-Ups.” Once you’ve done this, Mozilla Firefox will no longer show pop-ups when you visit websites or apps.


Mozilla Firefox blocks any pop-ups on your websites by default. If you’d like it to show those pop-ups, you will have to disable the built-in pop-up blocker first. We’ll show you how to do that in Firefox on desktop, iPhone, and iPad.

Disable Pop-Up Blocker in Firefox on Desktop

To turn off the pop-up blocker in Firefox on your Windows, Mac, Linux, or Chromebook computer, first, launch Firefox on your computer.

In Firefox’s top-right corner, click the three horizontal lines.

From the menu that opens, select “Settings.”

On the settings page, in the left sidebar, click “Privacy & Security.”

On the right pane, scroll down to the “Permissions” section. Here, at the bottom, disable the “Block Pop-Up Windows” option.

And that’s it. You have successfully turned off Firefox’s built-in pop-up blocker. Any site can now show pop-up windows when you visit them.

Allow Pop-Ups for Specific Websites on Firefox

One good thing about Firefox is that you can enable pop-ups for specific sites while blocking them on all other sites. If you’d like to do this, then next to the “Block Pop-Up Windows” option (this option must be enabled), click “Exceptions.” On the “Allowed Websites – Pop-Ups” window that opens, type the full address of the site where you want to enable pop-ups, click “Allow,” and then click “Save Changes.”

Firefox will now allow pop-ups from your specified sites while blocking them on all other sites. Enjoy!

If you use Chrome alongside Firefox, you can disable the pop-up blocker in Chrome, too.
