PROBLEM WITH FIREFOX O EXPLORER?? HELP!

Hello everyone, I have a problem with maximenu_ck, now I explain:

I am creating a site with joomla 2.5 and I installed firefox on a patch called filebug, until here everything ok, I create my menu, which fades to black and white on firefox I can see very well, when I open the site from the internet explorer 8 or 9, the menu is presented without any blue tinge.

From the console of joomla, I have tried to make the site compatible with explorer 7 or less, but nothing happens!

I hope for a response on your effective, I thank you in advance.

I can not give you the URL because the site is still locally
