Can't use IE8 & Firefox 3.6 after installing Onlinefamily

Please help!

 

Somehow after I installed OnlineFamlity, IE & Firefox can't access any websites anymore.  No matter it's parent's account or child's account.  Only Chrome (6.0) is functional.

 

I tried to disable OnlineFamliy add-on in Firefox and IE, but it did not help.

 

Why is that?   Nothing is changed before and after OnlineFamily installation.

 

Any one?
