Anything we can think of popup is simply possible using this plugin. Very attractive and easy to use popup builder I have ever used. It's kind of one many army tool which can be used to design any kind of popups we could use in a web page. !!Recommend!!

It's been a few months since I've been using the Firebox. I found the plugin very promising that you can easily use to create popups from the WordPress editor itself. Highly recommended!! And not only easy but also lightweight, so, no slowing your site down, that's what important these days.

I have tried other popup plugins (free and payed), most of them difficult to use or limited. Firebox is PERFECT. 100% recommended.

The firebox plugin is extremely useful and simple to use. I was able to set up popups for my customers in a matter of minutes. The availability of several popup designs and themes is also advantageous. For designs, Firebox is enough; you don't need many plugins. The firebox is definitely on my list of primary tools for plugins.

Just add FireBox to a client's website and am really impressed with it. Very easy to use and configure. My client asked to add a popup with a promo, even though I have use other popup plugins I was not really comfortable with any of them so start searching and found FireBox. Now I'm adding it to my list of 'basic tools' plugins! Alejandro Robles Web-Shop.cc Digital Marketing Agency
