You should be able to start browsing the web using Tor Browser shortly after running the program, and clicking the “Connect” button if you are using it for the first time.
If Tor Browser doesn’t connect, there may be a simple solution. Try each of the following:
Your computer’s system clock must be set correctly, or Tor will not be able to connect.
Make sure another Tor Browser is not already running. If you’re not sure if Tor Browser is running, restart your computer.
Make sure that any antivirus program you have installed is not preventing Tor from running. You may need to consult the documentation for your antivirus software if you do not know how to do this.
Temporarily disable your firewall.
Delete Tor Browser and install it again. If updating, do not just overwrite your previous Tor Browser files; ensure they are fully deleted beforehand.
If you still can’t connect, your Internet Service Provider might be censoring connections to the Tor network. Read the Circumvention section for possible solutions.
Tor Browser is under constant development, and some issues are known about but not yet fixed. Please check the Known Issues page to see if the problem you are experiencing is already listed there.
If the above steps do not help you solve the problem, you can contact Tor’s help desk. Send an email to help@rt.torproject.org with exact details of the problem, your operating system, and the steps you have already tried. Please only contact the help desk if you cannot find the answer to your question in this manual.
If possible, you should also include the “Tor log”, an automatically-generated list of Tor’s activity that can help diagnose the problem. To copy the Tor log, either:
click the button labelled “Copy Tor Log To Clipboard” that appears in the dialog window while Tor Browser is connecting to the network, or
if Tor Browser is already open, click on the Torbutton icon (the small green onion at the top left of the screen), then “Open Network Settings”, then “Copy Tor Log To Clipboard”.
You can now paste the Tor log into your support request.
