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.

The Connection Assist informs you about the state of your Internet connection.

Check your Internet Connection if it says 'Offline'. If your connection to the Tor Network is not established and it reads 'Not Connected' the following steps can be helpful.

Check browser version

It is often important to know what version of Tor Browser you are using, to help you troubleshoot a problem or just to know if Tor Browser is up to date. This is important information to share when raising a support ticket.

• When you have Tor Browser running, click on "Settings" in the hamburger menu (≡).
• Scroll down to the "Tor Browser Updates" section where the version number is listed.

Quick fixes

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 or instance of 'Tor' is not already running on your system. 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.
• If Tor Browser was working before and is not working now your system may have been hibernating. A reboot of your system will solve the issue.
• Delete Tor Browser and install it again. If updating, do not just overwrite your previous Tor Browser files; ensure they are fully deleted beforehand.

View Tor logs

In most cases, taking a look at the Tor logs can be helpful in diagnosing the issue. If you're having trouble connecting, an error message may appear and you can select the option to "copy Tor log to clipboard". Then paste the Tor log into a text file or other document.

If you don't see this option and you have Tor Browser open, you can navigate to the hamburger menu ("≡"), then click on "Settings", and finally on "Connection" in the side bar. At the bottom of the page, next to the "View the Tor logs" text, click the button "View Logs...".

Alternatively, on GNU/Linux, to view the logs right in the terminal, navigate to the Tor Browser directory and launch 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]

More information on this can be found on the Support Portal.

Is your connection censored?

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.
