MAFIAAFire Redirector is an extension for the Mozilla Firefox and Google Chrome web browsers. The software redirects links from domains that have been seized by governments to backup sites, in order to bypass the blocking. The software is open source.

MAFIAAFire offers domain owners a preemptive way to "safeguard" themselves from government-sponsored domain seizures. Domain owners can register their main site and their mirror site on the site MAFIAAFire.com before their domain is seized. If their domain gets seized, the add-on will automatically start redirecting to the mirror site. Theoretically, this means that site owners will have zero downtime if their main domain is seized and their users have the MAFIAAFire Redirector add-on.

In May 2011, the United States Department of Homeland Security has requested that Mozilla remove MAFIAAFire from its extensions directory, a request which Mozilla resisted.[1]

General information
MAFIAAFire works by downloading a list which contains the names of the "blocked" sites as well as the sites to redirect to. This list is downloaded every time the user's web browser starts up or every two days (although the user has the choice to force an update).
