In 2025, Tor faced some of the toughest censorship yet. From Iran’s wartime internet blackouts to Russia’s rapidly evolving blocking tactics. Tor’s anti-censorship team sprung into action and strengthened Snowflake, deployed the new Conjure pluggable transport, and made WebTunnel more wide available. Thanks to real-time monitoring, community feedback, and faster bridge distribution, Tor keeps people connected when it matters most. Want to help? You can support our mission by running a Snowflake proxy or hosting a WebTunnel bridge.
Starting with Tor Browser 16.0a1, the Tor Browser Alpha release channel will be based on Firefox Rapid Release rather than Firefox Extended Support Release. If you are an at-risk user, concerned about your privacy, or just need a web-browser that works reliably, you should not use Tor Browser Alpha and instead stick with Tor Browser Stable.
Join us for part 2 of State of the Onion: Community Day. Building on this year's theme, we've invited other members of the Tor community to share insights from their work and how they are supporting the fight to FREE THE INTERNET.
Tor is upgrading its relay encryption algorithm for improved
security. In upcoming releases, Arti and Tor will both support a new
encryption algorithm called Counter Galois Onion (CGO). CGO prevents
attackers from tampering with encrypted traffic, adds forward secrecy,
and brings Tor's encryption up to modern standards.
Mexico blocked Tor access to government websites citing security concerns. The current administration lifted the main block earlier this year, though some sites appear to remain restricted. Ironically, the government had previously used Tor for its own anti-corruption whistleblower system while blocking citizens. This is a guest post from our friends at Global Voices.
When censorship strikes, Tor provides a lifeline to access information--a lifeline to a FREE INTERNET. Tune in to this year's 2025 State of the Onion event to hear about how our teams and community work tirelessly behind the scenes to keep it alive.
