When 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。 你能看见一个把日志拷贝到剪切板的选项，然后你就可以将其粘贴到文字编辑器或邮件客户端。

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]
