50592 Firefox Compatibility Problems

I have a Suggest Script that works a bit like Google Suggest [login to view URL] It works great in Internet Explorer, but not any other major browsers. I need you to make it work in the other main browsers especially Firefox and Safari. Also Conqueror, Opera and netscape if you are a good enough programmer. The script consists of: 1) HTML form. 2) Javascript File 3) PHP file that processes the data 4) [login to view URL] with the words to be Suggested 5) [login to view URL] file to check against for abusive words The code you write will become my property after the project is finished.
