Starting from Friday May 3, a problem in Firefox and Tor Browser disabled all add-ons, especially NoScript which is used to:

• Strengthen Tor Browser against some JavaScript attacks that can lead to compromised accounts and credentials on websites.

• Enable or disable JavaScript on some websites using the NoScript interface, if you use it.

If NoScript is activated, the NoScript icon appears in the top-right corner and Tor Browser is safe:

If NoScript is deactivated, the NoScript icon is absent from the top-right corner and Tor Browser is unsafe:

Activate NoScript manually

To secure Tor Browser in Tails 3.13.1 or earlier, you must activate NoScript every time you start Tails:

1. Consulta l'indirizzo about:config in Tor Browser.

   

2. Fai clic sul bottone Accetto i rischi.

3. At the top of the page, search for xpinstall.signatures.required.

4. Double-click on the xpinstall.signatures.required line in the results to set its value to false.

5. Verify that NoScript is activated again.
