Tor Browser 是一款可匿名、可翻牆、隱藏 IP、防監控的網頁瀏覽器，開放原始碼，跨平台，支援 Windows、Mac OS X、Linux、Unix、BSD 以及行動裝置 Android 和 iOS 等作業系統。其英文名稱中的 Tor 是 The Onion Router (洋蔥路由器) 的縮寫，中文名稱叫做洋蔥路由瀏覽器。它是從 Mozilla Firefox ESR 瀏覽器修改而來，並由 Tor Project 開發人員做了許多安全性和隱私保護的調校，提供匿名瀏覽技術，讓使用者在瀏覽網站時可翻牆、隱藏 IP、防監控或側錄。
洋蔥路由瀏覽器在後台啟動 Tor 程序並透過其連接網路。一旦程式切斷連接，瀏覽器便會自動刪除敏感的隱私資料，如 cookie 和瀏覽歷史記錄。這款瀏覽器本身提供 SOCKS 代理服務，一些應用程式也可藉此使用 Tor 網路。Tor 的設計原意在於保障用戶的個人隱私，以及不受監控地進行秘密通訊的自由和能力。
洋蔥路由瀏覽器預設會啟用 HTTPS Everywhere、NoScript、TorButton、TorLauncher 等擴充套件，藉由停用 JavaScript、Java、Flash、Silverlight 以及某些特殊的控制碼來達到隱藏用戶真實 IP、避免網路監控及流量分析的目的，並以強制 HTTPS 加密連線的方式大幅提升上網時的安全性。洋蔥路由瀏覽器用戶的網際網路活動 (包括瀏覽網站、貼文以及即時訊息等通訊形式) 相對較難追蹤。

Tor Browser 原文簡介：
The Tor network is a group of volunteer-operated servers that allows people to improve their privacy and security on the Internet. Tor’s users employ this network by connecting through a series of virtual tunnels rather than making a direct connection, thus allowing both organizations and individuals to share information over public networks without compromising their privacy. Along the same line, Tor is an effective censorship circumvention tool, allowing its users to reach otherwise blocked destinations or content. Tor can also be used as a building block for software developers to create new communication tools with built-in privacy features.
Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor’s onion services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.
Tor can’t solve all anonymity problems. It focuses only on protecting the transport of data. You need to use protocol-specific support software if you don’t want the sites you visit to see your identifying information. For example, you can use Tor Browser while browsing the web to withhold some information about your computer’s configuration. Also, to protect your anonymity, be smart. Don’t provide your name or other revealing information in web forms.
