Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.
Note: You can also download the latest beta version, Tor Browser 9.5.3 Alpha here.
Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor's hidden services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.
Journalists use Tor to communicate more safely with whistleblowers and dissidents. Non-governmental organizations (NGOs) use Tor to allow their workers to connect to their home website while they're in a foreign country, without notifying everybody nearby that they're working with that organization.
Groups such as Indymedia recommend Tor for safeguarding their members' online privacy and security. Activist groups like the Electronic Frontier Foundation (EFF) recommend Tor as a mechanism for maintaining civil liberties online. Corporations use Tor as a safe way to conduct competitive analysis, and to protect sensitive procurement patterns from eavesdroppers. They also use it to replace traditional VPNs, which reveal the exact amount and timing of communication. Which locations have employees working late? Which locations have employees consulting job-hunting websites? Which research divisions are communicating with the company's patent lawyers?
A branch of the U.S. Navy uses Tor for open source intelligence gathering, and one of its teams used Tor while deployed in the Middle East recently. Law enforcement uses Tor for visiting or surveilling web sites without leaving government IP addresses in their web logs, and for security during sting operations.
Welcome Screen
Our old screen had way too much information for the users, leading many of them to spend great time confused about what to do. Some users at the paper experiment spent up to 40min confused about what they needed to be doing here. Besides simplifying the screen and the message, to make it easier for the user to know if they need to configure anything or not, we also did a 'brand refresh' bringing our logo to the launcher.
Censorship circumvention configuration
This is one of the most important steps for a user who is trying to connect to Tor while their network is censoring Tor. We also worked really hard to make sure the UI text would make it easy for the user to understand what a bridge is for and how to configure to use one. Another update was a little tip we added at the drop-down menu (as you can see below) for which bridge to use in countries that have very sophisticated censorship methods.
Proxy help information
The proxy settings at our Tor Launcher configuration wizard is an important feature for users who are under a network that demands such configuration. But it can also lead to a lot of confusion if the user has no idea what a proxy is. Since it is a very important feature for users, we decided to keep it in the main configuration screen and introduced a help prompt with an explanation of when someone would need such configuration.
As part of our work with the UX team, we will also be coordinating user testing of this new UI to continue iterating and make sure we are always improving our users' experience. We are also planning a series of improvements not only for the Tor Launcher flow but for the whole browser experience (once you are connected to Tor) including a new user onboarding flow. And last but not least we are streamlining both our mobile and desktop experience: Tor Browser 7.5 adapted the security slider design we did for mobile bringing the improved user experience to the desktop as well.
Other
- We ship the first release in Tor's 0.3.2 series, 0.3.2.9. This release includes support for the Next Generation of Onion Services.
- On the security side we enabled content sandboxing on Windows and fixed remaining issues on Linux that prevented printing to file from working properly. Additionally, we improved the compiler hardening on macOS and fixed holes in the W^X mitigation on Windows.
- We finally moved away from Gitian/tor-browser-bundle as the base of our reproducible builds environment. Over the past weeks and months rbm/tor-browser-build got developed making it much easier to reproduce Tor Browser builds and to add reproducible builds for new platforms and architectures. This will allow us to ship 64bit bundles for Windows (currently in the alpha series available) and bundles for Android at the same day as the release for the current platforms/architectures is getting out.

Those who remember SuperCalc have automatic membership in the 'I Remember When' club. SuperCalc was a spreadsheet program designed by Gary Balleisen and published in the early 1980s by a company called Sorcim. (The first edition was for the CP/M operating system.) In 1984 the product was purchased by Computer Associates, and they published it for several years. SuperCalc predates Excel by quite bit.
Many companies and individuals used SuperCalc, and have subsequently standardized on using Excel. If you have some old SuperCalc spreadsheet files laying around, you may be wondering how to convert them to Excel. Current versions of Excel don't include SuperCalc filters; they were last included in Excel 95.
Converting files if you still have SuperCalc installed on a system is a snap--all you need to do is export the SuperCalc workbook in Lotus 1-2-3 format, and then you can import it into Excel. Lotus filters are much more common in the Excel world than many other filters. You could also, if you have Excel 95 installed on an old system, try to do the conversion using that version of Excel, and then load the converted Excel file into a newer version of Excel.
If you have a very valuable file you need to convert, or if you have quite a few files to convert, you might give some thought to using a third-party company to do the conversion. A quick Google search for 'SuperCalc conversion' turns up quite a few potential resources for this approach.
