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.
... 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.
