Firefox
 

For those who haven't been firefox friendly and they have display issues, i'm wondering what programs are around that might analyze your code and display the errors to make your site firefox friendly.

The best thing you can do is just make sure your page passes validation.

There are a few firefox extensions that can make this easier.. check out the 'Web Developer Toolbar'. if your page passes validation you can chalk up any rendering problems to browser bugs, not your website code.

is it a script issue or a layout issue?
