Nagware do not have a place in AMO. It's different if it's a free software in Windows and asks you to buy a software. But Firefox is different, it is developed by a non-profit organization. Even if you say that your code is open source, with the "nags", you are destroying the spirit of open source software. If you really are short on money, then I suggest you do what NoScript and Adblock Plus do, ask for donation. You could do with your current business strategy, prioritize users who donated in terms of missed ad support.
Please don't see this review in a bad way. Think of it this way, you are driving users away with the nags. I just want to see this add-on rise again.
