You're welcome. In our site, it's due to this little script:
//Fix Firefox backButton Stupidity
if(window.addEventListener){window.addEventListener("unload",P7_FFfix,false);}
function P7_FFfix(){return;}

Unfortunately, the bug is a Firefox (and Safari/Chrome) one so our choice is
to rewrite our scripts or work around their deficiencies. If we do nothing,
then our scripts will not works correctly, which is probably worse -
especially in our line of business. We thought we'd give them a few "dot"
releases to fix it but they have not yet. I think you'll find most major
sites, including Adobe.com and Yahoo.com to have this "issue".

I would also consider contacting Mozilla as well.
