Google Web Designer Banner Taparea is not clickable in Firefox

Firefox have some problems in rendering the preserve-3d transform-style elements. So when we create an banner tap area in Google Web Designer, it become non-clickable in Firefox.

To solve it, you may:

Go to the Code View in Google Web Designer.
Look for this CSS class in the code: .gwd-page-content.
Set the transform-style as flat.
Republish the creative.
