My div background looks fuzzy in Firefox

Hi,
I've been looking everywhere to for a similar post and couldn't find one, please let me know if there is one around.

I would apreciate your help with this:
Why are my div backgrounds look fuzzy in Firefox and not IE ?
Here is an example:

As you can see my company logo is quite unclear in Firefox compared with IE where it looks to be fine.
I have this issue all over the site and I'm probably doing something wrong.
Thank you,

Looks fine to me. Either this is just a subtle way to get your link published for SEO, or your FF has weird settings.

Far from me to get traffic this way, that would be quite low.
But thanks a lot for taking the time to look into this, I took your advice and tested on different OS with FF and it looks to be fine.
I guess it has to be something with my local machine/install.
Thank you
C
