Firefox is configured to use a proxy server that can’t be foundCheck the proxy settings to make sure that they are correct. Check to make sure your computer has a working network connection. If your computer or network is protected by a firewall or proxy, make sure that Tor Browser is permitted to access the Web.

Here is where you check your Firefox connection settings:

  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

Firefox 56-59: In the search box at the top of the page on the right side, type proxy and Firefox should filter to the "Settings" button, which you can click.

Firefox 38-55: In the left column, click Advanced. Then on the right side, with the "Network" mini-tab active, click the "Settings" button.

In All Versions: The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".

Any difference?
