We have previously written about how to allow pop-ups on an iPhone, which will show you how to make that adjustment when you are using the default Safari Web browser. However, that change only applies to Safari. If you want to allow pop ups in the Firefox browser on your iPhone, then you will need to change a different setting.
Fortunately this setting occurs directly through the Firefox browser on the device, and can be completed with just a few steps. So if you are visiting a website in Firefox on your iPhone and need to be able to access a pop-up window that is currently being blocked, then our guide below will help you to find and disable the pop-up blocker in the Firefox browser.
How to Disable the Pop Up Blocker in the Firefox iPhone Browser
The steps in this article were performed on an iPhone 7 Plus, in iOS 10.2. The version of Firefox being used was the most current one available when this article was written.
Step 1: Open the Firefox iPhone browser.
Step 2: Touch the Menu icon at the bottom of the screen.
Step 3: Swipe left on the menu.
Step 4: Tap the Settings icon.
Step 5: Touch the button to the right of Block Pop-up Windows to allow pop ups in Firefox on your iPhone.
Note that this setting will remain active until you elect to turn it back on. If you are only making this change because you are visiting a specific site where you need that functionality, then I recommend going back to that menu immediately to turn the pop-up blocker back on.
