Tor Browser 3.6-beta-2 is released

The Tor Browser Team is proud to announce the second beta in the 3.6 series. Packages are available from the Tor Browser Project page and also from our distribution directory.

This release is an important security update over 3.6-beta-1. This release updates OpenSSL to version 1.0.1g, to address potential client-side vectors for CVE-2014-0160.

The browser itself does not use OpenSSL, and is not vulnerable to this CVE. However, this release is still considered an important security update, because it is theoretically possible to extract sensitive information from the Tor client sub-process.

This beta also features a Turkish language bundle, experimental Javascript hardening options, fixes for pluggable transport issues, and a fix for improper update notification while extracting the bundle over an already existing copy.

Here is the complete changelog since 3.6-beta-1:

  • All Platforms
    • Update OpenSSL to 1.0.1g
    • Bug 9010: Add Turkish language support.
    • Bug 9387 testing: Disable JS JIT, type inference, asmjs, and ion.
    • Update fte transport to 0.2.12
    • Update NoScript to 2.6.8.19
    • Update Torbutton to 1.6.8.1
      • Bug 11242: Fix improper "update needed" message after in-place upgrade.
      • Bug 10398: Ease translation of about:tor page elements
    • Update Tor Launcher to 0.2.5.3
      • Bug 9665: Localize Tor's unreachable bridges bootstrap error
    • Backport Pending Tor Patches:
      • Bug 9665: Report a bootstrap error if all bridges are unreachable
      • Bug 11200: Prevent spurious error message prior to enabling network.
  • Linux:
    • Bug 11190: Switch linux PT build process to python2
    • Bug 10383: Enable NIST P224 and P256 accel support for 64bit builds.
  • Windows:
    • Bug 11286: Fix fte transport launch error

Ways to get the Tor Browser Bundle

Below is a collection of resources that will help you get Tor up and running. We also discuss alternative approaches of downloading the Tor Browser Bundle and provide mirrors for all these resources in case torproject.org is blocked.

To start with, please look at Bundle Downloads and determine the best way for you to download the Tor Browser Bundle. After you have downloaded the bundle and before you install/extract it, you should also verify it to make sure the bundle you downloaded is genuine and has not been tampered with; this step is optional but recommended.

We have screencasts (video guides) that will help you with the installation and verification process on Windows, Linux and OS X.

GetTor

GetTor is a program for serving the Tor Browser Bundle through email. This is particulary useful if you cannot access torproject.org or any other mirrors.

To request a bundle from GetTor, send a blank email to gettor@torproject.org. GetTor will then respond with links to the Tor Browser Bundle for all platforms.

Note: GetTor was earlier restricted to requests from Gmail and Yahoo!. This is no longer the case and you can request for bundles from any email address, including Outlook.

Bridges

If you are unable to reach the Tor network after installation (Tor Launcher starts, however the green progress bar stops), you need to use bridges.

Acquiring Bridges

One way to find public bridge addresses is to send an email (from a Gmail or a Yahoo! address) to bridges@bridges.torproject.org with the line 'get bridges' by itself in the body of the mail.

You can also acquire bridges by visiting https://bridges.torproject.org/. If you see that this page is offline, please wait for a few minutes and try again.

Bridge Usage

1. Launch the Tor Browser Bundle
2. Click "Configure"
3. Click "Next" until you reach a page that reads "If this computer's Internet connection is censored, you will need to obtain and use bridge relays"
4. Enter the bridges you received from one of the methods above into the text box
5. Click "Connect"

Pluggable Transports

If you find that using standard bridges fails for you, you can try using the 3.6-beta-1 bundle located on the same downloads page listed above. These bundles included integrated pluggable transport support, and are useful in areas where standard bridges are blocked.

To activate pluggable transports in the 3.6-beta-1 bundle, follow the bridge directions above, however simply select "obfs3" or "fte" when you reach the bridge configuration page (instead of entering bridge addresses yourself).

Tor Browser 3.6-beta-1 is released

The Tor Browser team is proud to release the first beta in the 3.6 series. Packages are available from the Tor Browser Project page and also from our distribution directory.

This beta features fully integrated Pluggable Transport support, including an improved Tor Launcher UI for configuring Pluggable Transport bridges. The Pluggable Transport code is also fully disabled for users who do not configure them.

We believe that this approach will allow us to quickly turn 3.6 into a stable release, perhaps as soon as the next point release of TBB.

This release also changes the MacOS archive format from zip to DMG, which should improve installation usability for Mac users.

This release also includes important security updates to Firefox.

Tor Browser Bundle 3.5 is released

Update 12/20: Test builds of Pluggable Transport bundles are now available. See inline and see the FAQ link for more details.

The 2.x stable series of the Tor Browser Bundle has officially been deprecated, and all users are encouraged to upgrade to the 3.5 series.

Packages are now available from the Tor download page as well as the Tor Package archive.

For now, the Pluggable Transports-capable TBB is still a separate package, maintained by David Fifield. Download them here: https://people.torproject.org/~dcf/pt-bundle/3.5-pt20131217/. We hope to have combined packages available in a beta soon.

For people already using TBB 3.5rc1, the changes are not substantial, and are included below.

However, for users of TBB 2.x and 3.0, this release includes important security updates to Firefox. All users are strongly encouraged to update immediately, as we will not be making further releases in the 2.x or 3.0 series.

In terms of user-facing changes from TBB 2.x, the 3.x series primarily features the replacement of Vidalia with a Firefox-based Tor controller called Tor Launcher. This has resulted in a vast decrease in startup times, and a vast increase in usability. We have also begun work on an FAQ page to handle common questions arising from this transition -- where Vidalia went, how to disable JavaScript, how to check signatures, etc.

The complete changelog for the 3.x series describes the changes since 2.x.

The set of changes since the 3.5rc1 release is:

  • All Platforms
    • Update Tor to 0.2.4.19
    • Update Tor Launcher to 0.2.4.2
      • Bug 10382: Fix a Tor Launcher hang on TBB exit
    • Update Torbutton to 1.6.5.2
      • Misc: Switch update download URL back to download-easy

Tor Browser Bundle 3.5rc1 Released

The first release candidate in the 3.5 series of the Tor Browser Bundle is now available from the Tor Package Archive:
https://archive.torproject.org/tor-package-archive/torbrowser/3.5rc1/.

This release includes important security updates to Firefox.

Moreover, the Firefox 17esr release series has been deprecated by Mozilla. This means the imminent end of life for our 2.x and 3.0 bundle series. All 3.0 users are strongly encourage to update immediately, as we will not be making further releases in that series. If this release candidate survives the next few days without issue, this release candidate will be declared stable, and we will officially deprecate the current stable 2.x Tor Browser Bundles and declare their versions out of date as well.

Here is the complete changelog:

  • All Platforms
    • Update Firefox to 24.2.0esr

Tor is looking for a Browser Hacker and an Extension Developer!

The Tor Project has two browser-related job openings available!

We are looking for a C++ browser developer to work on our Firefox-based browser, and a Firefox extension developer to work on our growing number of Firefox extensions. Our ideal candidates would be comfortable in both roles, but we are also interested in hearing from people with either skillset.

On the C++ side, your tasks would include implementing new Firefox APIs and browser behavior changes; looking for and resolving web privacy issues; fixing bugs; responding on short notice to security issues; and helping to merge patches upstream.

On the extension development side, your primary tasks will include writing patches and UI improvements for Tor Birdy, Torbutton, HTTPS-Everywhere, Tor Launcher, and an OTR plugin for InstantBird. These improvements will primarily revolve around improving usability, Tor configuration, and security for our users.

Instructions on how to apply to the C++ position can be found on the browser hacker job posting. If you would prefer to focus on extension development, you should apply to the extension developer position.
