In places where Tor is blocked, people won't be able to connect to Tor because without enough bridges, the browser’s ability will be less reliable. However, bridges are also like ordinary Tor relays, in which they are run by volunteers.īecause the networks is running out of volunteers who maintain the bridges, users are at risk of not being able to connect to Tor. Unlike ordinary relays, bridges are not listed publicly for security and privacy reasons. "Thanks to our community of bridge operators, users in China, Belarus, Iran, and Kazakhstan can connect to the Tor network and access the free and open Internet," explained Tor. It's these bridges that provide access to users living in places where the Tor network is blocked. This is where we need your help."īridges are essentially the private Tor relays that serve as Tor Browser users' stepping stone into the Tor network. We therefore need a constant trickle of new bridges that aren't blocked anywhere yet. It's not enough to have many bridges: eventually, all of them could find themselves in block lists. Unfortunately, these numbers have been decreasing since the beginning of this year. "We currently have approximately 1,200 bridges, 900 of which support the obfs4 obfuscation protocol. In a blog post, the nonprofit Tor Project, the organization that maintains and develops the Tor software, said that it is running out of bridges. When Tor Browser users browse the web, the browser will first connects to a random publicly listed entry nodes, to then bounce that traffic through a randomly selected middle relay, before finally sending that traffic out to the public internet through the third and final exit node.
While there are other browsers that focus on the privacy of its users, none of them work in the same way as Tor.Īccording to Tor's about page, the Tor Browser works using the Tor network, which has virtual tunnels to pass users' internet activities. Using the Tor Browser, users can prevent their ISP and the government from knowing what websites they visit. When it comes to browsing the web, people can use a number of browsers to help them.īut among all the browsers they can choose, the Tor Browser should come first in the mind of those who wish to anonymize their internet activities.
