Tor Weekly News — November 27th, 2013

Welcome to the twenty-second issue of Tor Weekly News, the weekly newsletter that covers what is happening in the Tor community.

Round of updated Tor Browser Bundles

Mozilla put out an urgent security release of the stable Firefox branch with version 17.0.11esr. The stable version of the Tor Browser Bundle has been updated accordingly. The 2.4 release candidate also received an update, together with the latest incarnation of tor Both were then given a further update due to an issue on 64 bit GNU/Linux systems.

The 3.0 branch saw the release of 3.0rc1 which — on top of updating its base software — fixed a build reproducibility issue on Windows, and a few other small fixes.

An updated version of Tails and the pluggable transport bundle are still in the making at the time of writing.

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

Mike Perry wrote a blog post to announce two new positions available at the Tor Project: “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.”

Look at the job descriptions for more details and how to apply for these exciting opportunities to make Tor software even better.


Roman Mamedov reported that the Californian company Cloud Engines is now shipping a device called the “Safeplug”. Exactly how the device works is unclear, but according to their FAQ, it looks like a router which transparently directs its client connections through Tor.

Such an approach is known to be flawed. Sean Alexandre was prompt in reminding everyone that “application protocols can still reveal your identity”, and quoted the warning on Tor’s download page: “To avoid problems with Tor configuration, we strongly recommend you use the Tor Browser Bundle. It is pre-configured to protect your privacy and anonymity on the web as long as you’re browsing with the Tor Browser itself. Almost any other web browser configuration is likely to be unsafe to use with Tor.”

Aaron Gibson detailed other concerns, namely the absence of source code or design documents, the mandatory router registration procedure, issues with the automatic update system, and the terms of service. He also criticized the “torified everything” approach and outlined an alternative which he had discussed with Roger Dingledine: “providing a captive portal that would instruct a user to download a copy of TBB and use the local router device as a first hop into the Tor network, perhaps by configuring the device as a bridge.”

On the upside, Andrew Lewman views the product as “a fine test case for consumer-level torouter market analysis. It would be great to learn 6 months from now how many they sold and a summary of customer feedback.” Despite having “lots of concerns”, Andrew is “trying to discuss them with Cloud Engines” and praised the community for “doing a fine job of raising questions”.

Miscellaneous news

Tor help desk roundup

Echoing the tor-talk thread summarized above, multiple people asked whether or not the Tor Project could recommend the Safeplug device.

An OS X user asked if it was always necessary to open the Tor Browser folder in order to start the Tor Browser Bundle. It is possible to create an alias in Mac OS or a shortcut in Windows to the “Start Tor Browser” script and place that alias or shortcut in a convenient place,
such as the Desktop.
