Hi Gerald, To use a Pop-Up Blocker it´s the best you use an Add-On. To install an Add-On you must go to this page Install Ghostery and install this. It´s from the offical Mozilla Website, so it´s Virus free and safe. I hope I could help you Supporter_Alex

I have looked all over Firefox and I cannot find the pop-up blocker suction so I can turn it off or on I have been through the menu over and over with no results can someone please point me in the right direction thank you Gerald

On Firefox for Android, you may try this:

Type about:config with a : in the Location (address) bar Search dom.disable_open_during_load and set it to false

To enable the popup blocker again just toggle above preference back to true.

Firefox for Android has a popup blocker built in. That extension is a form of Ad blocker.
