A new release for the stable Tor Browser is available from the Tor Browser Project page and also from our distribution directory.
Tor Browser 4.0.5 is based on Firefox ESR 31.5.3, which features important security updates to Firefox. Additionally, it contains updates to Tor and NoScript.
Note to Tor Browser alpha users: There won't be a corresponding alpha release based on Firefox ESR 31.5.3 this time as we are currently in the midst of preparing releases based on ESR 31.6.0. Alpha users that can't wait another week are strongly recommended to use the Tor Browser 4.0.5 meanwhile.
Here is the changelog since 4.0.4:
- All Platforms
- Update Firefox to 31.5.3esr
- Update Tor 0.2.5.11
- Update NoScript to 18.104.22.168
