nice that you posted my question, but doesn't your support know the answer? i'm not looking for a forum, i need firefox tech support

Go read up on the 'HOSTS' file... or go get the program called 'Hostsman'. It will take care of all your blocking needs.

I think you misunderstood the "Ask a Question" as it is for posting a new thread on this Firefox support forum, not for some form of instant chat. Gave you links to such at https://support.mozilla.com/en-US/questions/842208
