Protecting your browsing activity involves more than hiding your IP address. Even the title of a browser window can give away what you are reading, and Tor Browser 16.0 introduces an option to make that information less accessible to other software on your computer.
The new release is available for desktop and Android, with redesigned settings and a move to Firefox ESR 153. The window-title protection is a desktop feature, and it addresses a privacy issue that many people probably have never considered.
Before getting into that, it helps to understand what Tor actually does. There are practical reasons to use it, even if your internet activity consists of reading ordinary websites and researching everyday questions.
Tor Browser is a modified version of Firefox that sends your browsing traffic through the Tor network. A typical connection to a public website passes through three servers, called relays, with layers of encryption helping separate your identity from your destination. The website sees an IP address associated with the Tor network instead of your own.
That arrangement reduces how much any individual relay knows about the connection. It also makes it harder for websites to use your usual IP address to connect your visits and infer your location, although it does not eliminate every possible way of identifying you.
The benefits can be quite positive. People facing internet censorship can use Tor to help reach blocked information, including news that authorities would prefer they never read. Others simply want more privacy while browsing, without having to justify why a particular subject interests them.
Consider someone researching a personal problem, exploring religious beliefs, or reading about a political movement. Those are ordinary activities, but they can be deeply private ones. Wanting some distance between that research and your identity should not be treated as suspicious.
As a journalist, I see value in giving people more control over how they access information. You should be able to read, question, and learn without feeling that every curiosity needs to become another entry in somebody’s profile of you.
There are limits, however. If you sign into an account associated with your name, that service still knows who you are, even though your connection comes through Tor. Hiding your usual IP address does not erase information you voluntarily provide to a website.
That brings us back to the new desktop feature. Browser windows normally use the title of the current page, and Tor says other applications or the operating system can read those titles without special permissions. The optional generic window titles setting replaces them with “Tor Browser,” reducing what that particular channel reveals.
You can find it under Privacy and security, within Protections from third-party applications. It remains opt-in because the project needs more feedback about possible effects on screen readers, application switchers, and customized desktop environments.
That accessibility consideration matters. Making windows harder to distinguish could create real friction for someone who depends on their titles to navigate, so users need a chance to evaluate the tradeoff. A privacy feature should be understandable and usable by the person it is supposed to protect.
The redesigned settings also bring clearer organization, with dedicated pages for areas such as appearance, downloads, and accessibility. Some options that could weaken privacy or increase fingerprinting exposure are hidden or carry warnings, while existing preferences remain saved.
For me, the window-title option is the most interesting part of this release because it makes an easily overlooked privacy problem concrete. It also illustrates why privacy requires attention to the software around a browser, as well as the connection leaving it. Tor Browser 16.0 does not promise an invisible user, but it gives people another specific choice about what their computer reveals.
