Unfortunately we do not provide our customers with any custom work due to our policy. We only do Support for our products if there are some issues in work, or some elements cause issues, etc.
In case you need to make some customizations you could try to figure this out on your own, which needs some skills in coding and programming.
In case if you believe our theme misses enough custom options to fully meet your needs you could involve/ask for help a third part developer to customize the theme the way you personally like.
Thanks for understandings and sorry for any inconveniences!
I was really looking for any acknowledgement as to whether it should work in firefox or not, since it works in other browsers and style sheet for the s code doesn’t seem to have any -moz specfic code for the shadow.
