Tor Browser 15.0.23 for Windows

Tor Browser 15.0.23 for Windows is the current stable release of the free browser from The Tor Project, built on Mozilla Firefox and designed for anonymous browsing. Download it only from torproject.org; below are answers to the questions people ask most before installing it.

What is Tor Browser?

Tor Browser is a web browser that connects to the Tor network instead of going straight to the websites you open. Your traffic passes through several volunteer-run relays before it reaches the site, so the site sees the address of the last relay rather than yours, and your internet provider sees that you use Tor but not which pages you visit. The browser is based on Firefox, which makes the interface familiar, but it comes with settings tuned for privacy and resists the tricks that sites use to recognise a returning visitor. The project dates back to 2008 and is maintained by The Tor Project, a non-profit organisation. People use it to protect their privacy on public Wi-Fi, to reach sites blocked in their country, or simply to keep advertisers from building a profile of their browsing. Journalists and activists rely on it too, which is why the project releases security updates so often.

Which Windows versions are supported?

• Windows 10 and Windows 11, in both 32-bit and 64-bit editions.
• Tor Browser is also available for macOS (10.15 and later), Linux and Android (5.0 or newer).

The official installation guide covers each platform.

How do I download and install it?

1. Open the official download instructions or go to torproject.org directly.
2. Download the Windows installer and run it; you can pick any folder, even a USB stick.
3. Start the browser and click Connect. If Tor is blocked where you live, the connection settings offer ways around the block.
4. Wait until the connection is ready, then browse as usual.

Is Tor Browser safe?

The official build is safe and open source. Fake copies are the real risk, so never take the installer from an unofficial site. Keep the browser updated, avoid installing extra add-ons that could identify you, and remember that logging in to a personal account tells that site who you are, Tor or not.

How often is it updated?

Very often. Several stable 15.0 updates came out in September 2026, and a separate alpha line tests upcoming changes. The release post for an earlier 15.0 update shows what a typical update contains.

Is it free?

Yes. Tor Browser is free software, released under GPL and BSD licences, with no ads or paid tier. The project is funded by donations and grants.

What are the pros and cons?

• Pro: strong privacy with no setup.
• Pro: free and open source.
• Pro: familiar Firefox-based interface.
• Con: pages load slower than in a normal browser.
• Con: some sites show extra captchas or block Tor users.

What are the alternatives?

If you want privacy features without the Tor network, look at Mullvad Browser, Brave Browser or LibreWolf in our browser listings. For everyday browsing, Mozilla Firefox is the base Tor Browser is built on.
