System requirements

Tor Browser is based on Mozilla Firefox's ESR (Extended Support Release), which periodically updates to include critical security updates from Firefox's main version. Due to these updates, older operating systems may eventually become incompatibile with newer versions of software dependencies that are only available in more recent OS versions. Maintaining support for outdated systems would compromise the security of Tor Browser, as it would require disabling newer security features and mechanisms that are crucial for protecting users' online anonymity.

Note: Support for Windows 7, 8, and 8.1 and macOS 10.12 to 10.14 is discontinued with Tor Browser 14. Users on these legacy operating systems will continue to receive security updates for Tor Browser 13.5 for until at least March of 2025. We strongly advise users to update in order to maintain access to the most recent updates and security features provided by Tor Browser.
