The Addons policy apparently has this to say about forks: > If the add-on is a fork of another add-on, the name must clearly distinguish it from the original and provide a significant difference in functionality and/or code. If anyone considers the addon to be in violation of this policy, they can use the “report for abuse” link halfway down the AMO page. Be sure to cite the policy paragraph and to politely explain why it violates the policy. The AMO review team may or may not agree, but at the very least they’ll consider it.
