Along with auto-play videos, pop-up windows are the bane of internet users. Most web browsers include the option to block pop-ups, and Firefox is no exception. Firefox is a free web browser developed by the Mozilla Foundation. As of May 2017, it is ranked the #2 desktop web browser in the world. Before you get too excited for Firefox, its 14.2% market share trails #1 Chrome by a healthy 49%. Firefox is a mere 5% above third place contender Internet Explorer.

Pop-ups are not only annoying but potentially dangerous too. As such, a user might expect to manage the pop-up blocker in any web browser under its Privacy or Security settings. The location of the option to block pop-ups in Firefox on your Windows PC, however, is in the Content panel under Options. It is important to note that the option to block pop-ups in Firefox is already on by default. You may need to modify this setting if someone turned it off for some reason, or if a site you trust requires a pop-up window to deliver important content. Here is how to block pop-ups in Firefox, and how to detect and manage pop-up exceptions for trusted sites.

Pop-up Detection

Firefox displays a pale yellow information bar across the top of the webpage when it detects and blocks a pop-up window.

For information about the blocked pop-ups, click the blocked pop-up icon block pop-ups in Firefox in the location bar or the Options button within the information bar. The pop-up options menu displays in a separate dialog. The options are to Allow pop-ups for the visited site, Edit the pop-up blocker options for the visited site, or to prevent the pop-up blocker information bar from displaying on the visited site when Firefox blocks pop-ups. You may also choose to Show the pop-up window that Firefox blocked.
