Have a look at the thread - MUST READ - How to post a Javascript question, especially:-

3) Do your homework first. Only post the part of the script you're having trouble with! There are generally two types of people- ones that simply dump their entire page or problem and expect everyone to spend hours solving everything for them, and those that do their own homework first, and only ask very specific, manageable questions. The later invariably gets more and better responses from others. When you're lazy, do not expect us to be hardworking for you.

You give us no clue as to what the issues with Firefox are supposed to be.


A teacher informed my son that "There are two words which you should never use in school homework - one is cool and the other is gross". "No problem", replied the boy, "What are the two words?"
