I'm going to be explaining something to someone on how to do something. And the first thing I'm going to say is: 1) To begin please download the firefox webbrowser - [Firefox Referral link] Am I allowed to do this? Am I also allowed to put: 1) To begin please download the firefox webbrowser - [Firefox Referral link] You must have the firefox web browser download to {I don't want to give away what I'm doing}. Is either of them against Google's TOC?
I am not sure about it; I suggest you contact adsense support and ask them whether its allowed or not. That will be a safe approach.
