<p>Because Tor routes your Internet traffic through 3 relays
before reaching its destination, the
connection is slower than when you are not using Tor.</p>

<p>See our documentation on
[[why Tor is slow|doc/anonymous_internet/tor/slow]].</p>

When you choose this option:

First, Tails synchronizes the clock of the computer automatically, because a correct time is needed to be able to connect to the Tor network.

Tails learns the current time by connecting to the captive portal detection
service of [Fedora](http://fedoraproject.org/static/hotspot.txt), which is used by most Linux
distributions. This connection does not go through the Tor network and is an
exception to our policy of only making Internet connections through the Tor
network.

<p>You can learn more about our security assessment of this time
synchronization in our [[design documentation about non-Tor
traffic|contribute/design/Tor_enforcement#non-tor-traffic]].</p>

If you choose instead to [[hide that you are connecting to Tor|tor#hiding]],
you might have to fix the computer clock manually.

If Tails fails to synchronize the clock because you have to sign in to the network using a captive portal, an error screen is displayed that helps you do so.

<p>Tails uses the [[default <i>obfs4</i> bridges from <i>Tor
Browser</i>|https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/blob/main/projects/tor-expert-bundle/pt_config.json?ref_type=heads]].</p>

See [[configuring a Tor bridge|tor#bridge]] below.

When *Tor Connection* fails to connect to Tor using public relays and default bridges, select **Configure a Tor Bridge** from the error screen.

To save the last Tor bridge that connected to Tor successfully, turn on the [[Tor Bridge|persistent_storage/configure#bridge]] feature of the Persistent Storage.
