The US Department of Homeland Security has asked the Mozilla Foundation to take down the "Mafiaa Fire" plugin, which automatically redirects browsers to the new URLs for sites that have had their .com and .net addresses seized in the latest round of the copyright wars. The Mozilla Foundation has firmly refused.

However, where ICE might have expected a swift take down from Mozilla, the legal and business affairs department of the tech company was not planning to honor the request so easily.

"Our approach is to comply with valid court orders, warrants, and legal mandates, but in this case there was no such court order," Anderson explains.

According to Anderson complying with the request without any additional information would threaten open Internet principles. So, instead of taking the add-on offline they replied to ICE with a set of 11 well-crafted questions.
