Hello,
Thank you for your question regarding your website being distorted in Mozilla. When I tested your site, it only displays correctly in IE, and seems distorted in Chrome and Mozilla.
I noticed your site is implementing "adobe flash" which pushed out an update recently to address bugs, and security (see more here).
Due to this, I recommend ensuring you are running the latest version of any software you are using to build your website.
Turning on error logging may provide a more detailed error message. Also, review any browser-specific scripts you may be running, and any changes you have recently made.
Thank you,
John-Paul
