The version of Tor currently shipped in Tails does not protect your anonymity as it should. **This vulnerability is critical.**
9
English type: Plain text
Until a future version of Tails is released (soon), the only way to have Tails protect your anonymity is to **upgrade Tor every time you start Tails**, by following the instructions bellow.

(Every time, really? Sure. Tails is amnesic: any change you make in it is lost upon restart.)

English type: Plain text
To upgrade Tor, start a *Root Terminal* from the *Applications* *Accessories* menu, and type the following command in there:
12
English type: Plain text
apt-get update && apt-get install tor && service tor start
13
English type: Plain text
... then type *Enter*, and wait until the upgrade is completed, which may take a few minutes. At this time, the Vidalia icon on the top right of the screen should have changed from the usual green onion to a grey, red-crossed one. Right click on it and choose *Exit* in the menu that opens. Then, start a new Vidalia from the *Applications* *Internet* menu.

Once this is done, you can safely use Tails as usual.
