Tor Browser 15.0 Portable is the latest major stable version of the Tor Browser — a free, open-source web browser designed to enhance online privacy, anonymity, and resistance to censorship by routing your internet traffic through the Tor network.

Review Of Tor Browser 15.0 Portable

It continues Tor’s mission of shielding users from surveillance, tracking, and location disclosure. Since the initial 15.0 launch, there have been minor maintenance updates (15.0.1, 15.0.2) that include essential security patches and dependency updates (e.g., Tor service updates, NoScript improvements, Firefox ESR patch backports). Tor Browser 15.0 is a significant upgrade built on Mozilla Firefox ESR 140 (Extended Support Release), incorporating a year’s worth of upstream improvements while preserving Tor’s privacy-focused core.

Please do not torrent over Tor. Tor Browser will block browser plugins such as Flash, RealPlayer, QuickTime, and others: they can be manipulated into revealing your IP address. We do not recommend installing additional add-ons or plugins into Tor Browser. Plugins or addons may bypass Tor or compromise your privacy. Tor Browser already comes with HTTPS-Only mode, NoScript, and other patches to protect your privacy and security.

Features Of Tor Browser 15.0 Portable

Desktop (Windows, macOS, Linux):

• Vertical tabs: Tabs can now be stacked in a sidebar for easier navigation instead of the traditional top row.

• Tab groups: Organize open tabs into collapsible, named and color-coded groups.

• Unified search button: New address bar integration that allows quick switching between search engines, bookmarks, open tabs, and quick actions.
  All tabs remain private and are cleared when you close the browser, preserving anonymity.

Enhanced Privacy on Android

• Screen lock: Adds an optional biometric or passcode lock to protect your open Tor session if you switch away from the app without closing it.

• Sessions are still clear on close for privacy.

Security & Technical Changes

• WebAssembly (Wasm) handling is now controlled by NoScript, the built-in security extension — this maintains a reduced attack surface while keeping trusted components like the PDF viewer functional.

• Continued commitment to audit and review upstream changes from Firefox before inclusion.

Platform Support Changes

Tor Browser 15 is the last major release to support:

• Android 5.0 — 7.0

• x86 CPU architectures on Linux and Android
  Future releases (starting with version 16) will drop these older platform versions to modernize the codebase and improve security.
