facebookcorewwwi.onion is a site that allows access to Facebook through the Tor protocol, using its .onion top-level domain.[1][2] In April 2016 it had been used by over 1 million people monthly, up from 525,000 in 2015.[1] Neither Twitter nor Google operate sites through Tor, and Facebook has been applauded for allowing such access,[3] which makes it available in countries that actively try to block Facebook.[4]

In October 2014, Facebook announced[5] that users could connect to the website through a Tor onion service using the privacy-protecting Tor browser and encrypted using HTTPS.[6][7][8] Announcing the feature, Alec Muffett said "Facebook's onion address provides a way to access Facebook through Tor without losing the cryptographic protections provided by the Tor cloud. […] it provides end-to-end communication, from your browser directly into a Facebook datacentre."[6] Its network address – facebookcorewwwi.onion – is a backronym that stands for Facebook's Core WWW Infrastructure.[5]

Prior to the release of an official .onion domain, accessing Facebook through Tor would sometimes lead to error messages and inability to access the website.[1] There are numerous reasons to use the Tor-protocol for legitimate purposes, such as for increased anonymity when connecting to Facebook.[9] ProPublica explicitly referenced the existence of Facebook's .onion site when they started their own onion service.[10]

Connecting to Facebook through Tor offers a way to access the site with a higher level of protection against snooping and surveillance from both commercial and state actors.[11] The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor.[11] As of its 2014 release the site was still in early stages, with much work remaining to polish the code for Tor-access. It has been speculated that other companies will follow suit and release their own Tor-accessible sites.[11]
