I am using self-hosted confluence server. My custom.css changes are all good in chrome/safari.
Problem: My custom.css file does not render in FIREFOX/IE. I am providing both the senerios below.
Please replicate the issue at docs.zetaapps.in
Chrome - It renders the css file, so our custom changes are all good.

Firefox - It is not showing css file at all. Please help here.

**********Please help resolve this issue since IT IS A BLOCKER*********
