What Tor Browser does
Tor Browser is an open-source browser from the Tor Project that routes supported browser traffic through the Tor network. A destination generally sees a Tor exit relay rather than the user's direct address, but this is not an anonymity guarantee. Accounts, browser changes, downloaded or opened files, other applications, endpoint compromise, traffic correlation, and user behavior can disclose identity or activity. Installing extensions or changing anti-fingerprinting defaults can also make a browser more distinguishable.
This record identifies Tor Browser 15.0.22 packages for Windows x86_64 portable, macOS, and Linux x86_64 from the Tor Project distribution archive. The current publisher download page links each package and its detached.asc signature. This record does not provide a locally verified hash or signature result. The Tor Project verification guide identifies signing-key fingerprint EF6E286DDA85EA2A4BA7DE684E2C6E8793298290; users must obtain and verify the key and signature themselves. This audit did not perform that verification or run the packages.
The Windows item is explicitly the portable build, the macOS item is a DMG, and the Linux item is an upstream tarball rather than a distribution package. Tor connectivity is required to browse, reach onion services, obtain updates, and refresh network information. Session data clearing does not remove downloaded files, bookmarks, operating-system traces, malware, or activity outside Tor Browser. Consult the Tor Browser Manual and support documentation for the current threat model before high-risk use.
