Facebook[1]’s onion address is the central concept in this text. An “onion address” is a unique type of URL utilized for accessing sites via the Tor network, providing enhanced privacy and security. In 2014, Facebook unveiled its own onion address, facebookcorewwwi.onion, making it one of the pioneering major corporations to take this step. This initiative was intended to minimize errors when reaching Facebook through Tor and to differentiate legitimate Tor users from botnet accounts. As of 2016, the onion address of Facebook was being used by over a million individuals each month. Due to vulnerabilities in version 2, the address was upgraded to a version 3 onion address in May 2021. The updated address is facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion. While it has been lauded for enabling users to circumvent censorship, it should be noted that not all tech firms, such as Google[2], run sites via Tor.
The Facebook onion address located at facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion (formerly facebookcorewwwi.onion) is a site that allows access to Facebook through the Tor protocol, using its .onion top-level domain.
