Problem with webfonts in firefox and links in IE

Hi people I'm currently making a website for a school project but I'm having the following problems.

1. Webfonts looking terrible in Firefox on Windows 7.

2. IE showing a thick white border around last 2 links in left menu.

Maybe someone have experienced something similar and found a w开发者_如何学编程orkaround or simply know how to fix this.

Best regards, Alexander Freiling

So far -webkit-font-smooth is the only thing I've seen that helps with webfonts. Unfortunately, it only seems to work in Safari and Chrome at the moment. There is a font-smooth property in CSS3, but none of the browsers have implemented it yet.
