Facts checked 8 Oct 2026

In short

Tor Browser is free; the vendor calls it open-source software³.
Desktop builds exist for Windows (.exe), macOS (.dmg) and GNU/Linux (.tar.xz), and Android installs from Google Play or F-Droid².
It is based on Firefox ESR and routes your traffic through the Tor network⁵.
Windows 10 or 11 is recommended; Windows 8.1 and older are no longer supported¹⁰.
The Safer level turns off JavaScript on non-HTTPS sites, and Safest turns it off on all sites⁹.

Tor Browser suits people who want traffic routed through the Tor network and fingerprint-resistant defaults, and who accept slower browsing and fewer conveniences^4,5. It is free³. The catch: the vendor's pages describe no sync, no password manager and no tab tools, and it lists no iOS app^1,11.

Best for: People who need anonymity more than convenience.

Vendor claims. We show them, but they earn no points.
