Tor Browser Bundle 4.0

Browse the web anonymously with the custom and private web browser from the Tor project
Tor Browser Bundle is a free and platform-independent application designed to allow users to browser the Web anonymously through the powerful Tor network on the Linux, Microsoft Windows and Mac OS X operating systems, without the need to use any third-party software.

It is a freely distributed, yet not open source graphical software, a mix between the well known Mozilla Firefox web browser and the Tor application, enabling users to surf the Web anonymously from the comfort of their Linux desktops.

Detailed installation instructions for each of the supported operating systems is provided on the project’s homepage, along with the respective binary packages, supporting the 64-bit and 32-bit hardware platforms and many languages.

It is a portable software, allowing users to use directly from a USB flash drive, running a pre-configured web browser to protect their anonymity. The Tor software is the key component of Tor Browser Bundle, protecting users by bouncing their communications around a distributed network of relays, which are run by volunteers all around the world.

When you open the application for the first time, it will ask if you want to immediately connect to the Tor network and start browsing the Web anonymously, or if you want to tweak your network settings, in case the respective computer its censored, proxied or filtered.

Once you hit the Connect button, the software will connect to the Tor network and in a few seconds it will close the connection dialog and open the actual web browser, which is based on an ESR (Extended Support Release) version of the Mozilla Firefox project.

To verify if your connection is indeed anonymous, you can access the website, wich will display the current IP address you’re using at that moment, as well as the geographical location.

Overall, Tor Browser Bundle is a really powerful application for Mozilla Firefox users who don’t want to configure the Tor network separately on their Linux-based operating system. Happy anonymous surfing!

What's New in This Release:
  • This release features important security updates to Firefox. Additionally, due to the POODLE attack, we have also disabled SSLv3 in this release.
  • The primary user-facing change since the 3.6 series is the transition to Firefox 31-ESR.
  • More importantly for censored users who were using 3.6, the 4.0 series also features the addition of three versions of the meek pluggable transport. In fact, we believe that both meek-amazon and meek-azure will work in China today, without the need to obtain bridge addresses.
  • This release also features an in-browser updater, and a completely reorganized bundle directory structure to make this updater possible. This means that simply extracting a 4.0 Tor Browser over a 3.6.6 Tor Browser will not work. Please also be aware that the security of the updater depends on the specific CA that issued the HTTPS certificate (Digicert), and so it still must be activated manually through the Help ("?") "about browser" menu option. Very soon, we will support both strong HTTPS site-specific certificate pinning (ticket #11955) and update package signatures (ticket #13379). Until then, we do not recommend using this updater if you need stronger security and normally verify GPG signatures.
