Blur a Group on Firefox

Does anybody have some code that works to blur a group on firefox?

I can blur a group in google chrome and other browsers, but not firefox.

I can blur an image in firefox and other browsers, but not a group.

I installed a free blur plugin and it works, but just not for groups in firefox.

My goal is to accomplish this task without purchasing a paid plugin.

Bootstrap currently works around several outstanding browser bugs in major … Firefox . focus events should not be fired at the document object.

I am sorry but I don’t understand the comments. I am not a programmer and so I don’t know how I would use bootstrap in bubble or how to fire a focus event at a document object.

Do you know of any code that can be used in bubble to set a blur on a group element that works in firefox?
