<title>Circumvention</title>

<p>
Direct access to the Tor network may sometimes be blocked by your Internet
Service Provider or by a government. Tor Browser includes some
circumvention tools for getting around these blocks. These tools are called
“pluggable transports”. See the <link xref='transports'>Pluggable
Transports</link> page for more  information on the types of transport
that are currently available.

  </p>
  <p>
  To use pluggable transports, click "Configure" in the Tor Launcher
  window that appears when you first run Tor Browser.
  </p>

  <p>
  You can also configure pluggable transports while Tor Browser is
  running, by clicking on the green onion near your address bar and
  selecting “Tor Network Settings”.

  <p>
  Select “yes” when asked if your Internet Service Provider blocks
  connections to the Tor network.

  pluggable transport options to choose from.

<title>Which transport should I use?</title>
<p>
Each of the transports listed in Tor Launcher’s menu works in a different
way (for more details, see the <link xref="transports">Pluggable
Transports</link> page), and their effectiveness depends on your
individual circumstances.
</p>
<p>
If you are trying to circumvent a blocked connection for the first time,
you should try the different transports: obfs3, obfs4, ScrambleSuit, fte,
meek-azure, meek-amazon.
</p>
<p>
If you try all of these options, and none of them gets you online,
you will need to enter bridge addresses manually. Read the <link 
xref='bridges'>Bridges</link> section to learn what bridges are and how
to obtain them.
