New Release: Tor Browser 16.0

2026-10-29T00:00:00Z

Tor Browser 16.0 is now available for Desktop and Android. This is our first stable release based on Firefox ESR 153, incorporating a year's worth of changes that have been shipped upstream in Firefox. As part of this process, we've also completed our annual ESR transition audit, where we reviewed and addressed over 270 Bugzilla issues covering changes in Firefox that could negatively affect the privacy and security of Tor Browser users.

The ongoing development of Tor Browser is made possible thanks to the support of our community. Every donation helps power the tools that let people browse freely and privately. Consider joining thousands of others who have already made a small contribution towards building a better internet for everyone.

What's new for Desktop?

Redesigned Settings

Tor Browser connects millions of people to the Tor network (and by extension, the free and open internet) out of the box. However, for those who need to circumvent advanced censorship, boost their security level, or tailor their browsing experience, clear and easy-to-use Settings are essential. To that end, Tor Browser 16.0 introduces a complete redesign of the Settings experience based on a parallel redesign shipped in Firefox in June. Improvements include a cleaner layout, updated navigation, and clearer labels and descriptions aimed at making settings easier to find, understand, and manage. Other noteworthy changes include:

The long-standing "General" page has been retired, with its contents distributed across new pages for Appearance, Downloads, Tabs and browsing, Accessibility and Languages.
Pages and components that are unique to Tor browser like Connection and Security Level have been rebuilt from scratch using Firefox's new components so they look and feel consistent with the rest of Settings.
Some settings that, if enabled, could compromise your privacy or make your browser easier to fingerprint have either been hidden or feature clear warnings.

Fear not: your existing preferences will remain saved even if the original setting has moved or changed, and you can use the search bar at the top of Settings to find anything you're struggling to track down.

Generic window titles

Another new addition to Settings is the option to use generic window titles, which can be found under Privacy and security → Protections from third-party applications. Like most browsers, Tor Browser uses the title of the page you're currently viewing for the names of its windows. However, other applications on your computer or your operating system itself can read these titles without special permissions. When enabled, this option simply replaces all window titles with "Tor Browser" — preventing other software from snooping on your browsing history. As always, for more comprehensive protection from third-party applications on your device, we recommend using Tails.

For now, this option is strictly opt-in, as we did not have sufficient time during this release cycle to properly evaluate potential side-effects for users. In particular, we worry that enabling this setting may reduce the browser's usability for those who rely on accessibility tools (e.g. screen-readers) or those with highly customized systems (e.g. less-popular desktop managers, application switchers, etc). If you are one of these users, we would ask that you try using this setting, and report back any bugs or usability issues you find!

📣 Generic window titles have also been upstreamed to Firefox as part of the Tor Uplift Project. Advanced Firefox users can enable this feature by opening about:config and setting privacy.exposeContentTitleInWindow (for normal windows) and privacy.exposeContentTitleInWindow.pbm (for private browsing windows) to false.

New user manual

The Tor Browser manual, which can be found by visiting about:manual or through the application menu (☰) → Help → Tor Browser manual, has also received a complete revamp. Since the release of our new Support portal in 2025, the team has had to maintain two sets of documentation: one for the traditional manual that's available to read in Tor Browser, and another for the new Support site. With this release, we've solved that problem by replacing the older material in the Tor Browser manual with our latest and greatest help content from the new Support site. Like the previous iteration of the manual, the new version is bundled with Tor Browser for Desktop so it can be read offline, which comes in particularly handy when troubleshooting issues that prevent you from connecting to the Tor network.

Linux on ARM

Finally, after a year of testing, Tor Browser 16.0 now features native support for Linux computers with 64-bit ARM (AArch64) processors, such as Raspberry Pis and Apple Silicon Macs running Linux. If you have been relying on Tor Browser Alpha for support for these devices, we recommend switching over to the stable release channel unless you plan to continue testing Alpha releases. Meanwhile, Tor Browser 16.0 follows Firefox in ending support for 32-bit x86 Linux computers. Fortunately, very few people should be affected, as we currently receive around 200 update checks from this platform a day, down from a peak of around 4,000 in 2019. Most remaining 32-bit users should be able to switch to the 64-bit version unless they're running outdated hardware or versions of Linux.

What's new for Android?

Tor Browser for Android has also benefited from Mozilla's ongoing work to modernize Firefox, as seen in the Settings redesign on desktop. Over the past year, Firefox has been gradually transitioning to Jetpack Compose — Google's newest framework for building native Android interfaces. In this release, we've made significant progress applying the same changes to Tor Browser. As a result, large swaths of Tor Browser's user interface has been updated to Material Design 3 — the latest iteration of Google's design language for Android — with more yet to come in future releases.

Google Play limits the size of apps distributed as APKs to 100 MB. Since Firefox for Android continues to grow with each release, keeping Tor Browser within this limit has been an ongoing challenge — for example, this issue has prevented us from bundling Tor Browser's manual on Android so that it can be accessed offline. Nevertheless, we've found various ways to reduce the size of our Android package over the years and stay within the limit. Most recently, this involved carefully and creatively compressing some of the built-in resources Firefox uses to display its interface.

What's in the works?

Tor Browser users can expect additional improvements over the next few months as we continue to refine the new Settings experience for desktop and Material Design 3 for Android. If you find a bug or have a suggestion for how we could improve this release, we'd love to hear your feedback.

The team is also working hard on a new and improved circuit display, coming soon to Tor Browser Alpha, which integrates site information directly into the circuit panel and can visualize more complex multi-path circuits. Multi-path circuits use additional relays to split your traffic into two paths that converge on a single exit, improving both connection speed and reliability. These circuits already exist for regular websites (but not onion sites) and are randomly assigned based on network availability. Although Tor Browser's traditional circuit display can only show a single path at a time, you have likely benefited from a multi-path circuit without even knowing it. What's more, this exciting update will mark the debut of the circuit display on Tor Browser for Android, which has been exclusive to desktop until now.

New Release: Tails 7.15.1

2026-10-23T00:00:00Z

This release is an emergency release to remove a compromised certificate authority.

Changes and updates

Update Tor Browser to 15.0.26, which fixes CVE-2026-113470.

On October 17, Mozilla blocked the certificates of eMudhra, a certificate authority that had its intermediate certificates compromised. Tor Browser 15.0.26 now blocks all eMudhra certificates as well.

Using one of the compromised intermediate certificates, an attacker could impersonate any website, even if the connection is secured with HTTPS.

This attack could be performed by a Tor exit node, the Internet service provider of an exit node, or a government. Onion sites are not vulnerable.

We are not aware of this attack being used by exit nodes so far.
Update the certificate authorities to block all eMudhra certificates in other applications.

In addition to Tor Browser , other applications rely on the certificate authorities included in Tails with the ca-certificates Debian package to secure their connections.

Get Tails 7.15.1

To upgrade your Tails USB stick and keep your Persistent Storage

Automatic upgrades are available from Tails 7.0 or later to 7.15.1.
If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a manual upgrade.

Tor is Powered by you: One donation today can impact 4M+ people

2026-10-13T00:00:00Z

Unlike Big Tech, Tor has never and will never sell your data to make money. 6,490 donors, and thousands of volunteer relay operators and others, keep Tor powered for 4M+ at any given moment* at zero cost to users.

You can ensure people worldwide can exercise their human rights to digital privacy and access to information by making a donation today. Every donation, of any size, makes a difference.

As a 501(c)(3) nonprofit, the Tor Project relies on donations to power its tools – the Tor network, Tor Browser, Tails OS, and the Tor ecosystem. These tools are trusted by millions and always free to use, without collecting, selling, trading, or renting any of your data for profit. Read our 2023-2024 financials to be confident your investment is being stewarded with the utmost importance.

In the last year we have reached some major milestones thanks to your support:

Tor VPN beta extends Tor protections beyond the browser. It offers device-level network protection on Android, helping bring Tor's protections to messaging apps, social media, email, and other mobile services of a user's choosing. Learn more about what makes our per-app isolation different from commercial VPNs, the surprising UX lesson when trying to bypass blocks, and the mobile foundation we're building for what's next.
Privacy Resilience Grants: Dispersed $23,201 to support 8 Tor partners in conducting Tor activities on the ground. Among these groups, women activists in Bolivia have adopted Tor tools, shifting the thinking of using other tools for power and resistance. Meanwhile, journalists in Afghanistan have reduced their reliance on VPNs, and have begun using Tails OS to securely share on the ground information globally.
Funding internet freedom: Our first crowdfunding round in partnership with Funding the Commons raised more than $200k for projects working across privacy, censorship circumvention, secure communications, and public-interest digital infrastructure. This is Tor’s first attempt at building a new funding infrastructure for the internet freedom community.

All of these major milestones have a real life impact on people globally. People who need privacy for their safety, people who rely on Tor tools to be connected to the world, and people who are casual users seeking an alternative to Big Tech.

“The police state is vigorously spying on people. Without Tor we would be shut off from the world, no one hearing our voice.”

– Iranian Tor user**

“I desperately needed a means to secure my online privacy because I am a cyberstalking victim. I started using Tor to protect my privacy and protect me from abuse.”

– Anonymous Tor user**

A statement on the Tor Project's relationship with Mullvad

2026-10-09T00:00:00Z

Recent concerns about a political donation by a Mullvad co-founder have raised questions about the Tor Project's funding relationship with the company. We are not terminating the relationship but are setting clear boundaries on our relationship with Mullvad.

Members of the Tor community have asked us to explain how continued collaboration with Mullvad fits with the Tor Project's human rights mission. We have heard both calls to end the relationship and concerns about what that would mean for Tor's work and the communities affected. We want to explain our decision to continue our technical collaboration with Mullvad and acknowledge the difficult trade-offs behind it. Our decision followed a thorough due diligence process that involved extensive discussions with community members, staff, and the board, a staff survey, and detailed financial analysis and scenario planning.

The Tor Project’s mission is to advance human rights and freedoms. We build privacy and anti-censorship tools that people use to protect themselves from repression and surveillance, and express themselves freely. We will continue this work alongside communities whose rights are under threat.

While Tor defends free speech, not all speech is equally compatible with our mission. We strongly oppose rhetoric that threatens other human rights and freedoms.

The work to promote and preserve the human right to privacy, free speech, and free access to information online is severely under-resourced. This work requires and benefits from collaboration across organizations. Sometimes that work requires making difficult compromises to advance specific goals we know will benefit our communities in the long run.

We are continuing our technical collaboration with Mullvad to sustain work that Tor users and contributors depend on. This collaboration has helped improve the structure, maintainability, and auditability of Tor Browser’s codebase, expanded feedback from users beyond Tor Browser’s core audience, and created a lower-risk environment to test features that may later benefit Tor Browser users. It also gives more people access to online privacy through an additional free, open-source tool that serves different user needs. We recognize that the potential benefits to Mullvad of such a collaboration are difficult for some in our community to accept. Our responsibility is to ensure that this collaboration does not compromise our mission or the Tor Project's independence.

Tor Project has paused proactive co-branding with Mullvad. That pause applies to joint promotional activity while the technical collaboration continues in alignment with our narrowly scoped agreement. We have also reviewed how Mullvad Browser is described and endorsed on our owned channels, and clarified language suggesting broader alignment between our values. These changes are intended to describe the relationship more accurately and avoid notions of implied endorsement.

We know this decision will not satisfy everyone. Continuing the collaboration carries a cost to trust for some in our community, and we take that seriously. We are grateful to the members of our community who have raised concerns, asked hard questions, and reminded us what is at stake. Those concerns are shaping our path forward. Tor’s mission has always required both principle and pragmatism. We will continue to defend privacy, anonymity, freedom of expression, and access to information while making clear that our collaborations must serve, and never obscure, our human rights commitments.
