Firefox Referral and Label

[thegreatpretender]

I have a java card game website... I'm thinking of putting a firefox referral button in there. Do you think it is ok if I put a sentence something like "This game runs better with firefox browser" just above the button? Well, I tried my application with both ie and firefox and indeed, it works better with firefox than running with ie.

IMHO for referrals it's even ok to say "Click here and install NOW!"

When I read Google Program Policies, Referrals are considered as Google Ads (which are not allowed to label), but I saw a few websites actually ask users to download and install the software.

Can anyone verify this?

Thanks.
