Tor 浏览器可以帮助人们访问所在地区被封锁的网站。 大多数时候，只需下载 Tor 浏览器，您就可以使用它去访问被屏蔽的网站。 在被严重监视的地区，我们提供许多规避监管的选项，譬如 可插拔传输。

参阅 Tor 浏览器用户手册 关于 审查 的章节获得更多信息。

如果您的连接出现问题，一则错误信息会弹出，您可以选择“将 Tor 日志复制到剪切板上”选项。 然后粘贴 Tor 日志到文本文件或者其他文档格式中。

If you don't see this option and you have Tor Browser open, you can navigate to the hamburger menu ("≡"), then click on "Preferences", and finally on "Tor" in the side bar. 在此页面的底部，“查看 Tor 日志”字样旁边，点击“查看日志”按钮。

Alternatively, on GNU/Linux, to view the logs right in the terminal, navigate to the Tor Browser directory and launch the Tor Browser from the command line by running:

‪./start-tor-browser.desktop --verbose

or to save the logs to a file (default: tor-browser.log)

‪./start-tor-browser.desktop --log [file]

您应该能够在 Tor 日志中发现这些常见问题（请在 Tor 日志里寻找如下所示的错误）:

Common log error #1: Proxy connection failure

2017-10-29 09:23:40.800 [NOTICE] Opening Socks listener on 127.0.0.1:9150
2017-10-29 09:23:47.900 [NOTICE] Bootstrapped 5%: Connecting to directory server
2017-10-29 09:23:47.900 [NOTICE] Bootstrapped 10%: Finishing handshake with directory server
2017-10-29 09:24:08.900 [WARN] Proxy Client: unable to connect to xx..xxx..xxx.xx:xxxxx ("general SOCKS server failure")

如果您看见这些提示出现在您的日志里面，这意味着您连接 SOCKS 代理失败了。 如果您的网络连接需要设置 SOCKS 代理，请确认您代理服务器的信息正确。 如果您的系统不需要代理，或者您不敢肯定，请尝试直接连接 Tor 网络。

Common log error #2: Can’t reach guard relays

11/1/2017 21:11:43 PM.500 [NOTICE] Opening Socks listener on 127.0.0.1:9150
11/1/2017 21:11:44 PM.300 [NOTICE] Bootstrapped 80%: Connecting to the Tor network

11/1/2017 21:11:44 PM.500 [NOTICE] Bootstrapped 85%: Finishing handshake with first hop
11/1/2017 21:11:45 PM.300 [WARN] Failed to find node for hop 0 of our path. Discarding this circuit.

如果您看见这些提示出现在您的日志里面，这意味着您的 Tor 无法连接到 Tor 网络中的第一个节点。 这可能意味着您处于有审查的网络中。

请尝试通过网桥连接，这应该能解决问题。

Common log error #3: Failed to complete TLS handshake

13-11-17 19:52:24.300 [NOTICE] Bootstrapped 10%: Finishing handshake with direc Tor y server 
13-11-17 19:53:49.300 [WARN] Problem bootstrapping. Stuck at 10%: Finishing handshake with directory server. (DONE; DONE; count 10; recommendation warn; host [host] at xxx.xxx.xxx.xx:xxx)

13-11-17 19:53:49.300 [WARN]  1 connections died in state connect()ing with SSL state (No SSL object)

如果你在 Tor 日志里看见这句话，这意味着 Tor 和目录服务器无法完成 TLS 握手。 使用网桥可能会解决这个问题。

Common log error #4: Clock skew

19.11.2017 00:04:47.400 [NOTICE] Opening Socks listener on 127.0.0.1:9150 
19.11.2017 00:04:48.000 [NOTICE] Bootstrapped 5%: Connecting to direc Tor y server

如果您看见这些提示出现在您的日志里面，这意味着您的系统时间设置错误。 请确认您的时间设置是正确的，包括正确的时区。然后重新启动 Tor。

网桥是不在 Tor 公共目录里列出的中继节点。

这意味着政府或 ISP 阻止 Tor 网络的尝试不能简单的封锁所有网桥。 如果你处于某个压迫政权中，或是担心被发现自己正在和 Tor 中继的 IP 地址连接，你可能需要使用网桥。

网桥就是有些许不同的中继。 查看我该如何运行网桥以获得指南。

一些国家，包括中国和伊朗，已经发现了检测和屏蔽 Tor 网桥的方法。 Obfs 代理服务器网桥通过增加一层混淆来解决这个问题。 需要一些额外软件和设置来运行 obfsproxy 网桥。 See our page on pluggable transports for more info.

Snowflake is a pluggable transport available in Tor Browser to defeat internet censorship. Like a Tor bridge, a user can access the open internet when even regular Tor connections are censored. To use Snowflake is as easy as to switch to a new bridge configuration in Tor Browser.

This system is composed of three components: volunteers running Snowflake proxies, Tor users that want to connect to the internet, and a broker, that delivers snowflake proxies to users.

Volunteers willing to help users on censored networks can help by spinning short-lived proxies on their regular browsers. Check, how can I use Snowflake?

Snowflake uses the highly effective domain fronting technique to make a connection to one of the thousands of snowflake proxies run by volunteers. These proxies are lightweight, ephemeral, and easy to run, allowing us to scale Snowflake more easily than previous techniques.

For censored users, if your Snowflake proxy gets blocked, the broker will find a new proxy for you, automatically.

If you're interested in the technical details and specification, see the Snowflake Technical Overview and the project page.

Snowflake is available in Tor Browser stable for all platforms: Windows, macOS, GNU/Linux, and Android. You can also use Snowflake with Onion Browser on iOS.

If you're running Tor Browser for desktop for the first time, you can click on 'Tor Network Settings' on the start-up screen and then select 'Use a bridge'. Click on 'Select a built-in bridge' and choose 'snowflake' from the dropdown menu. Once you've selected Snowflake, scroll up and click 'Connect' to save your settings.

From within the browser, you can click on the hamburger menu ("≡"), then go to 'Preferences' and go to 'Tor'. Alternatively, you can also type about:preferences#tor in the url bar. Check 'Use a bridge' and 'Select a built-in bridge'. Then select 'snowflake' from the dropdown menu.

If your internet access is not censored, you should consider installing the Snowflake extension to help users in censored networks. When you run Snowflake on you regular browser, you will provide connection as a proxy to an entry node in the Tor Network, and that’s all.

Add-on

Firstly make sure you have WebRTC enabled. Then you can install this addon for Firefox or the add-on for Chrome which will let you become a Snowflake proxy. It can also inform you about how many people you have helped in the last 24 hours.

Web page

In a browser where WebRTC is enabled: If you don't want to add Snowflake to your browser, you can go to https://snowflake.torproject.org/embed and toggle the button to opt in to being a proxy. You shouldn't close that page if you want to remain a Snowflake proxy.

You might be on a network that is blocking the Tor network, and so you should try using bridges. Some bridges are built in to Tor Browser and requires only a few steps to enable it. When you open Tor Browser for the first time, click "Tor Network Settings". Under the "Bridges" section, select the checkbox "Use a bridge", and choose the "Select a built-in bridge" option. From the dropdown, select whichever pluggable transport you'd like to use. Once you've selected the pluggable transport, scroll up and click "Connect" to save your settings.

Or, if you have Tor Browser running, click on "Preferences" (or "Options" on Windows) in the hamburger menu (≡) and then on "Tor" in the sidebar. 在“网桥”界面中，点击“使用网桥”的复选框，并从“选择一个内置网桥”选项中，在下拉菜单里选择任意一个您想要使用的可插拔传输。 当你关闭标签页时你的设定会自动保存。

如果您需要其他的桥接，你可以从桥接网站 上查询。 关于网桥的更多信息请参阅 Tor 浏览器用户手册。

Users in China need to take a few steps to circumvent the Great Firewall and connect to the Tor network. First, get an updated version of Tor Browser: send an email to gettor@torproject.org with the subject "windows zh-cn" or other operating system (linux or macos)

After installing Tor Browser, you will probably not be able to connect directly to the Tor network, because the Great Firewall is blocking Tor. Therefore, the second step will be to obtain a bridge that works in China.

There are three options to unblock Tor in China:

1. Snowflake: uses ephemeral proxies to connect to the Tor network. It's available in Tor Browser stable version (Desktop and Android). You can select Snowflake from Tor Browser's built-in bridge dropdown.
2. Private and unlisted obfs4 bridges: users will need to request a private bridge to frontdesk@torproject.org with the phrase "private bridge" in the subject of the email or, if they are tech-savvy, they can run their own obfs4 bridge from outside China. It's important to note that bridges distributed by BridgeDB (HTTPS, email), and built-in obfs4 bridges bundled in Tor Browser most likely won't work.
3. meek-azure: it looks like you are browsing a Microsoft website instead of using Tor. However, because it has a bandwidth limitation, this option will be quite slow. You can select meek-azure from Tor Browser's built-in bridges dropdown.

If one of these options below is not working, check your Tor logs and try another option.

有些网站因为他们无法分辨出普通 Tor 用户和机器人的区别而屏蔽了 Tor 用户的访问。 我们能让网站解封 Tor 用户的最成功的手段是让用户直接联系网站管理员。 这么做也许能解决你的问题：

“嗨！我正在使用 Tor 浏览器访问 xyz.com ，不过似乎你们并没有允许 Tor 用户访问。 我建议您重新考虑这个决定；Tor 被世界各地的人用来保护隐私和对抗审查。 封锁 Tor 用户意味着也可能封锁了希望在专制国家自由的浏览互联网的用户，希望隐藏自己避免被发现的研究人员、记者、举报人和社会活动家，或只是希望不被第三方跟踪的普通人。 请采取强硬立场支持数字隐私和互联网自由，以及允许 Tor 用户访问 xyz.com，谢谢。”

另外，银行等比较敏感的网站经常进行地区范围的屏蔽（例如如果你平时只在某个特定的国家使用他们的服务，从其他国家进行访问时你的账号可能就会被冻结）。
